Top 3 questions answers- 1) The acid needed here is Nitric acid and the base needed here is Ammonium hydroxide. The chemical reaction is- HNO3 + NH4OH = NH4NO3 + H2O. 2) a) Vinegar contains acetic acid. b) Milk contains lactic acid. c) Tomatoes contain oxalic acid. d) Apples contain malic acid. 3) Toothpaste is basic in nature. Our mouth contains many acids. We know that a base can neutralize an acid. In this case it becomes neutral and that's why Toothpaste help prevent decay teeth. And another acid that tomatoes contain I think other than oxalic acid is citric acid since it is sour. Sir would you please check my answers?
1. Ammonium chloride(weak base)+ Nitric acid (strong acid)will give Ammonium nitrate(acidic salt)+ water. 2.(a)Acetic Acid,(b)Lactic Acid,(c)Oxalic Acid,(d)Malic Acid. 3.Toothpaste is actually basic in nature. So, it helps in removing the bacteria that is present in the teeth that contains acid. So, the toothpaste will neutralise the acid and helps in preventing tooth decay.
1)hcl+naoh=n2naoh+h20 2)a) vinegar=acetic acid,milk-lactic acid,tomatoes- oxalic acid,apples- citrus acid 3) toothpaste contains salt which help neutralize the acids and bases presnt in the saliva. thats why brushing our teeth with toothpaste prevents decaying of teeth.
Wow...thanks a lot sir! It helped me a lot 1. Nitric acid and ammonium hydroxide ---- HNO3+NH4OH----->NH4NO3+H2O 2.a) vinegar-acetic acid b) milk-lactic acid c) tomatoes-oxalic acid d) apples-malic acid 3. Bacteria in your mouth causes tooth decay by changing the leftover food on our tooth into acids. These acids causes tooth decay. If we brush our teeth with toothpaste which is a base neutralizes the acid and hence tooth decay can be prevented.
Sir excellent explanation. And your answers are≈ (1)-Ammonia and Nitric acid.[HNO³+NH³--NH4NO] (2)- -Vinegar~Acitic acid. -Milk~Lactic acid. -Tomato~Oxalic acid+Maleic acid. -Apple~Maleic acid. (3)-Because it contains Sodium fluoride (NaF). Which kills bacteria present on our teeth. Thanks a lot sir.
1..HNO3+NH4OH---- NH4(NO3) 2.vinegar-acetic acid Milk-lactic acid Tomatoes-oxalic acid Apple-malic acid 3.tooth paste(base) helps in avoid decaying of enamel of teeth as the microbes in our mouth produces acid which cause decay of enamel,and this base neutralizes acid..
Tomato sauce has vinegar in it which is used in many materials like pickles as a preservative. Thus, tomato sauce has oxalic and acetic acid. 1.) Ammonium Hydroxide + Nitric Acid ----------> Ammonium Nitrate + Water + Heat NH4OH + HNO3 ---------> NH4NO3 + H2O + Q 2.) a.) Vinegar isused in many materials like pickles as a preservative and has Acetic acid in it. b.) Milk or curd has lactic acid in it c.) Tomato sauce has Oxalic acid present in it d.) Apples is mostly determined by the Malic acid present in it 3.) Major tooth issues like tooth decay is caused when we eat sugary foor such as chocolates, sweets, etc. The bacteria's act upon this sugar and transform it into acid because ( bacteria + sugar = acid ), and this acid eats up the tooth leading to tooth decay. As Toothpaste is a base, it prevents the acid from eating up the tooth by neutralizing it's effect. Hence, Toothpaste prevents tooth decay
Q1)HNO3=acid NH3=base So,HNO3+NH3-----NH4NO3 Q2)a)vinegar-acetic acid b)milk-lactic acid c)Tomato-oxalic acid d)apples-malic acid Q3)Because toothpaste contains fluoride,fluoride fights against the bacteria present in our teeth and helps to prevent the decay in teeth
1)HNO3 +NH3 = NH4NO 2) a) vinegar : acetic acid b)milk : lactic acid c)tomatoes : oxalic acid d) apples : malic acid 3)When food particles decay in our teeth , the level of acidity in our mouth rises .This leads to tooth decay. Toothpaste are basic to nature . So, this neutralizes the acids and help prevent tooth decay . Sir very understandable. Please make more videos like this ...
1)NH4NO3____NH4OH+HNO3 2)vinegar -acetic acid Milk. -lactic acid Tomato - oxalic acid Apple -malic acid 3)Tooth paste contain salt it neutrize acid and base so it help to prevent dacay ofteeth

Super amazing sir ....... can you please answer me the first question In ketchup citric acid is present but it also contain vinegar which means it has acetic acid too 2-vinegar contain acetic acid ....... milk contain lactic acid ......... tomatoes contain oxalic acid and apples contain malic acid 3-fluoride use in toothpaste make the outer hard surface of teeth more resistant towards the acid produced by bacteria present in teeths and gums Kindly sir reply about question no.1 👍👍👍👍
Great to hear that you liked the video! Very good your answers are correct :) Ketchup is made from tomatoes, which contain oxalic acid. Acetic acid is also usually added in the ketchup. You can also try the Quiz for this video at www.manochaacademy.com
1. Acid: ammonium(NH3) Base: nitric acid( HNO3) 2. a)Acetic acid b)Lactic acid c)Oxalic acid and 9 more acids d)Malic acid 3.The toothpaste we use in our daily life is a base, the action of bacteria occurs in an acidic medium in our tooth, to prevent tooth decay the base which presents in the toothpaste neutralizes the acid present in our tooth.
1. Ammonium nitrate (NH4NO3) is indeed soluble in water. It is formed by the reaction between ammonium hydroxide (NH4OH) and nitric acid (HNO3). 2. Vinegar contains acetic acid, milk contains lactic acid, tomatoes contain oxalic acid, and apples contain malic acid. These acids contribute to the characteristic taste of the respective food items. 3. The bacteria living on the teeth and gums produce acid, which can erode the tooth enamel and cause dental decay. Fluorine, which is contained in toothpaste, neutralizes this acid and helps to prevent tooth decay.
1.HCL and NH4OH 2.Vinegar-Acetic acid CH3COOH Milk-Lactic acid C3H6O3 Tomatoes-Oxalic acid Apples-Malic acid 3.It helps to prevent decay of teeth from excess acid in our tooth by neutralizing it.
Since the reaction is between an acid and a base, it should produce salt and water right? Shouldn't the acid be HNO3 and base NH4OH to produce NH4NO3 and H20
Q1) Ammonia solution and nitric acid Q2a) Acetic acid b) Lactic acid c) Oxalic acid d) Malic acid Q3) Toothpaste contains a base which neutralizes the acidic substances we eat and prevents tooth decay. Thank you sir. The video was extremely helpful.
Q.3 Before we brush our teeth the pH of saliva is less than 7 that is acidic. The toothpaste contains the alkali substance which neutralizes the acid and prevent from tooth decay. If you got your answer hit a like!!!👍👍👍👍👍
Q1=Nitric acid and Ammonium hydroxide Q2=a) Acetic acid b) Lactic acid c) Oxalic acid d) Malic Acid Q3= It neutralizes the acids left over from our food
1. Acid HNO3 and Base NH4OH 2. a) accetic acid b) Lactic acid c)oxalic acid d) don't know 3. Because to decay tooth bacteria in mouth secretes acid and toothpaste is a base. Therefore, neutralization reaction takes place and our tooth doesn't get decay. Thankyou sir for your explanation
1.NH3+NO3=NH4NO3 2.a)venigar=acetic acid B)Milk=lactic acid C)tomatoes =oxalic acid D)apples=malic acid 3) this is because when we not brush it releases acid and while we are doing brush Toothpaste is base both acid and base becomes neutralize
Answer 1nitric acid and ammonium hydroxide is used to form salt ammonium nitrate and the chemical reaction is NH4N03+H2O. 2.a.Acetic acid b.Lactic acid c. Oxalic acid d.malic acid 3.Toothpaste which is a base helps prevent tooth decay by neutralizing the excess acid realised by the bacteria present in our mouth.
1)ammonium nitrate NH3+HNO3=NH4NO3 Ammonia (base)+nitric acid (acid) =ammonium nitrate 2)a)vinegar-acetic acid B)milk-lactic acid C)tomatoes-oxalic acid D)apples-malic acid 3)when ph of mouth saliva falls below 5.5,the enamel gets weathered. Toothpastes which are generally basic are used for cleaning the teeth that can neutralize the excess acid and prevent tooth decay. Are my answers correct sir
1.NH4OH+HNO3~NH4NO3+H2O 2.(a) acetic acid (b) lactic acid (c) oxlic acid (d) malic acid 3.when we eat food, food and sugar produces acid. The acid will form in mouth to neutral the mouth from acid we use tooth paste as mild base.
1) Base is NH3, Acid is HNO3 Chemical reaction:- NH3 + HNO3 ➡️ NH4NO3. 2) (a) vinegar - acetic acid (b) milk- lactic acid (c) tomatoes - oxalic acid (d) apple - malic acid. 3) Fluoride is a compound that is added to toothpaste to reduce decay. Fluoride becomes incorporate into our teeth as they develop and makes them more resistant to decay. -thank you Rishita Nath (class 10)
When pH value of mouth is below 5.5 bacteria present in mouth produce acid by degration of sugar and food particles remain in the mouth. The best way to prevent this to clean the mouth after eating food. Using toothpaste, which are generally basic neutralize the access acid and prevent tooth decay
Q1 Acid + Base = Salt + water Let's take given products to determine reactant which are acid and base so by double displacement We get eq NH*4NO*3+ H2O= NH*4OH + HNO *3 Acid is nitric acid and base is ammonium hydroxide Q2. a. Acetic acid b. Lactic acid c. Oxalic acid d. Malic acid Q3. Fluorine is the halogen forming salts used tooth paste so when it combines to phosphorus and calcium present in teeth forms fluorapatite which is crystalline mineral like salt. That fluorine compound prevent us to tooth decay 🇵🇰
The more I say it is less.... I really appreciate you for your kind work to help the unaffordable during this pandemic.... Thanks sir.... Hope you succeed on gaining success
Ans 1. HNO3 +NH3 => NH4NO Ans 2. Vinegar. Acetic acid Tomatoes. Citric acid and Malic acid Milk. Lactic acid Apples. Malic acid Ans 3. The Fluride prevents teeth from toothaches because it makes teeth strong and more resistant to acid
tomato sauce has both citric and malic acids . toothpaste contains flouride making it a base and helps to remove tooth decay by neutralising the effect of the acid
The other acid that found in tomato is malic acid HW: 1)The acid and a base formed are HNO3 and NH4Cl Respectively 2) vinegar - acetic acid Milk - latic acid Tomatoes - Oxalic acid Apples- Malic acid 3) Toothpaste contains calcium fluoride and many other bases which is helpful to Neutralise our teeth and prevent from tooth decay :)❤
How does tooth paste help in tooth decaying answer: - the nature of the toothpaste is alkaline, which is basic . They neutralize the acid produced by bacteria in mouth.
2.vinegar acetic acid Lactic acid: milk Tartric acid: 🍎 3.the base can nuetrolize an acid and those germs which are acids can be nuetrolised and this prevents tooth decay.thanks sir
1.HNO3+ NH4OH - NH4NO3+H2O 2.a) acetic acid b) Lactic acid c) Oxalic acid d) malic acid 3. Bacteria present in our mouth may react with sugar and generate acids.This can corrode our tooth enamel which leads to tooth decay. Toothpastes which are basic in nature can neutralize these acids and thus can prevent our tooth from decaying.😅
Toothpaste helps prevent tooth decay through its active ingredients, which work in several ways: 1. Fluoride: Most toothpaste contains fluoride, a mineral that strengthens tooth enamel, making it more resistant to acids produced by bacteria in the mouth. Fluoride also helps remineralize areas where enamel has started to break down, reversing early signs of decay. 2. Antibacterial agents: Toothpaste often contains compounds like triclosan or stannous fluoride that help reduce the number of harmful bacteria in the mouth. These bacteria contribute to plaque formation and acid production, both of which lead to tooth decay. 3. Physical Abrasives: The mild abrasives in toothpaste help scrub away plaque and food particles from teeth, reducing the potential for bacteria to grow and cause cavities. 4. Prevents Acid Erosion: Toothpaste helps neutralize acids produced by bacteria in the mouth, which can erode enamel and lead to cavities. By brushing with toothpaste regularly, you help protect your teeth from the factors that cause decay.
Really nice video.. The most effective thing in the video is that you have performed the things practically rather than a neat display which is very very helpful... Really nice
Q2) Answer - (a) Acetic Acid , (b) Lactic Acid , (c) Citric Acid, (d) Malic Acid Q3) Answer - when we are not brushing our teeth the microorganisms starts feeding on the remains or which is stuck between our teeth and they start producing acid this acid which is produced from microorganisms will lead to the teeth decay, so to neutralise the acid, we have to use base (toothpaste)
Q1:HNO3+NH4OH=NH4NO3+H20 Q2: Vinegar: oxalic acid and acetic acid Milk:Lactic acid Tomatoes:Malic acid, oxalic acid,citric acid ascorbic acid Apples:Malic acid and tataric acid Q3: Toothpastes defend the tooth from teeth decay because it contains fluoride which is a weak base and neutralizes the effects of the bacteria in the mouth which is acidic
1)NH4OH + HNO3 = Ammonium nitrate + H2O 2)a. Acetic acid b.Lactic acid c.Oxalic acid d.Malic acid 3)The covering of the teeth is enamel which is a base. The cavities are acidic in nature. So, it will corrode the enamel layer giving us some teeth sensitivity. So, it is better you brush your teeth with toothpaste because toothpaste is basic helping the enamel and prevent corroding.
Actually,we eat the food which contains acids and if the acidic nature is more in our teeth it may cause tooth decay so we use the basic paste to neutrilize it
Thank you very much It was very helpful to me. You are teaching I a excellent way that our school teacher are not able to explain like this 👌👌👌👌👌👌👌👌👌👌😃😃😃😃👍👍👍👍👍👍👍👍🙏🙏🙏🙏👍👍👌👌👌

love this channel..... HE USES ONLY ENGLISH WHILE SPEAKING....explanation is superb
tq, sir..............
Thanks sir . Even my science teacher couldn't explain it so well 😊
It's my pleasure
It very well
Kya Bhai apne sir ka he bejti kr rhe hoo

Thanks 😊 sir 😄😊
1. Acid HNO3 and Base NH4OH
2. a) accetic acid b) Lactic acid c)oxalic acid d) don't know
3. Because to decay tooth bacteria in mouth secretes acid and toothpaste is a base. Therefore, neutralization reaction takes place and our tooth doesn't get decay.
Thankyou sir for your explanation
My science exam is tomorrow and now I am watching this 🙂
same dude
Bhaii lode lage hue h 😂✋
same

Excellent teaching, Sir!It has made chemistry easier..Please make more videos
We will
I agree with you
@@ManochaAcademy you should
Sir please do more videos on biology... It is helpful for competitive exams...
1.NH3+NO3=NH4NO3
2.a)venigar=acetic acid
B)Milk=lactic acid
C)tomatoes =oxalic acid
D)apples=malic acid
3) this is because when we not brush it releases acid and while we are doing brush
Toothpaste is base both acid and base becomes neutralize
Answer
1nitric acid and ammonium hydroxide is used to form salt ammonium nitrate and the chemical reaction is NH4N03+H2O.
2.a.Acetic acid
b.Lactic acid
c. Oxalic acid
d.malic acid
3.Toothpaste which is a base helps prevent tooth decay by neutralizing the excess acid realised by the bacteria present in our mouth.

Posted 4 years ago but it is still fresh for 2022-23 batch like. Thnq so much sir ❣️😊😊
This video should be reached to every child in the whole world!!!
This makes me learn anything easier.....
Thanks for liking
Still this video is gold for all of us
Thank you so much Sir
For excellent explanation that you give us..............👏👍🏻
1)ammonium nitrate
NH3+HNO3=NH4NO3
Ammonia (base)+nitric acid (acid)
=ammonium nitrate
2)a)vinegar-acetic acid
B)milk-lactic acid
C)tomatoes-oxalic acid
D)apples-malic acid
3)when ph of mouth saliva falls below 5.5,the enamel gets weathered. Toothpastes which are generally basic are used for cleaning the teeth that can neutralize the excess acid and prevent tooth decay.
Are my answers correct sir
Thanks for your answers
This helps me alot I have problems in first question but now it is clear
Sir it is very useful for me to understand Acid, Base and Salt I scored 20 out of 19 thanks sir
1.NH4OH+HNO3~NH4NO3+H2O
2.(a) acetic acid (b) lactic acid (c) oxlic acid (d) malic acid
3.when we eat food, food and sugar produces acid. The acid will form in mouth to neutral the mouth from acid we use tooth paste as mild base.
No you are wrong 😂😂
Wrong
no you are totally wrong
1) Base is NH3,
Acid is HNO3
Chemical reaction:-
NH3 + HNO3 ➡️ NH4NO3.
2) (a) vinegar - acetic acid
(b) milk- lactic acid
(c) tomatoes - oxalic acid
(d) apple - malic acid.
3) Fluoride is a compound that is added to toothpaste to reduce decay. Fluoride becomes incorporate into our teeth as they develop and makes them more resistant to decay.
-thank you
Rishita Nath (class 10)
Sir your are so good.. the way of your explanation was so easy to understand quickly.. thank you sir
Thanks and welcome
Sir you are not so strong 💪💪
When pH value of mouth is below 5.5 bacteria present in mouth produce acid by degration of sugar and food particles remain in the mouth. The best way to prevent this to clean the mouth after eating food. Using toothpaste, which are generally basic neutralize the access acid and prevent tooth decay
Q1
Acid + Base = Salt + water
Let's take given products to determine reactant which are acid and base so by double displacement
We get eq
NH*4NO*3+ H2O= NH*4OH + HNO *3
Acid is nitric acid and base is ammonium hydroxide
Q2. a. Acetic acid
b. Lactic acid
c. Oxalic acid
d. Malic acid
Q3. Fluorine is the halogen forming salts used tooth paste so when it combines to phosphorus and calcium present in teeth forms fluorapatite which is crystalline mineral like salt. That fluorine compound prevent us to tooth decay 🇵🇰
1.HNO3+NH3 forms NH4NO.
2.a) acetic acid.
b) lactic acid.
c) oxalic acid .
d) malic acid.
3.They neutralise the effect of acid. 0:04 0:04 0:04
Wrong in 1st question
The more I say it is less.... I really appreciate you for your kind work to help the unaffordable during this pandemic.... Thanks sir.... Hope you succeed on gaining success
You are very welcome
No problem sir
@@dr.muller2110 same..
Sir you can say important points also sir plz
@@dr.muller2110 Q
1: HNO3 + NH3 ➡️ NH4NO
2: a: acetic acid. b: Lactic acid c: oxalic acid d: Malic acid
3: Toothpaste have Flouride which prevent the decay of the teeth.
Sir you are the best teacher I have seen
Hope you become the best teacher in RUclips
😘😘😘
Thanks a ton
@@ManochaAcademy welcome sir
Ans 1. HNO3 +NH3 => NH4NO
Ans 2.
Vinegar. Acetic acid
Tomatoes. Citric acid and Malic acid
Milk. Lactic acid
Apples. Malic acid
Ans 3. The Fluride prevents teeth from toothaches because it makes teeth strong and more resistant to acid
Congratulations 🎊 ❤🎉😂😅
My all doubts regarding this topic is clear now. Ty sir.
We will understand easily. When we're compared our teachers. So tq so much sir. This is for tenth class am right.
Yes class 7th
Sir ,ur teaching way is superb and very helpful video 😊 Thanks a lot sir ..
It's my pleasure
sir please speak in hindi
tomato sauce has both citric and malic acids . toothpaste contains flouride making it a base and helps to remove tooth decay by neutralising the effect of the acid
Very good explanation sir
It's also easy to understand
I request you to make more such videos
on chemistry
We will
This video is very helpful to know about acids and bases. I want to know that which acids present in milk and apple.
Thanks a lot :) Apples contain malic acid and milk has lactic acid.
@@ManochaAcademy Thank you sir
Sir what you add in 2 glass
They way he speaks is just like a ... infact I don't know what to call it. God bless you sir
Thanks for liking
This man is my teacher's favorite. He just plays this video answers any questions we have, and gives us work.
lol same
ur class is more more better than every other class.. Keep going🤗🤗🤗🤗🤗🤗🤗🤗
Thank you sir for this amazing video
It's really very helpful
THANKS
Most welcome
The other acid that found in tomato is malic acid
HW:
1)The acid and a base formed are HNO3 and NH4Cl Respectively
2) vinegar - acetic acid
Milk - latic acid
Tomatoes - Oxalic acid
Apples- Malic acid
3) Toothpaste contains calcium fluoride and many other bases which is helpful to Neutralise our teeth and prevent from tooth decay :)❤
Acid present in Tomato is Oxalic acid😊
Number 1 question:
HNO3 + NH4CL= N2(NH4)+ CLNO3+ H2.😅 16:37
Vinegar=acetic acid
Milk=lactic acid
Tomato=oxalic acid
Apple=malic acid
SIR UR SO GREAT I LIKE U R TEACHING THAN OUR SCHOOL TEACHERS 🙏🙏🙏🙏🙏 WE LOVE U SO MUCH THANKU SIR
Most welcome
2.vinegar ... acetic acid
Tomatoes. .. oxalic acid.
Milk....lactic acid
Apples ....malic acid
How does tooth paste help in tooth decaying answer:
- the nature of the toothpaste is alkaline, which is basic . They neutralize the acid produced by bacteria in mouth.
2.vinegar acetic acid
Lactic acid: milk
Tartric acid: 🍎
3.the base can nuetrolize an acid and those germs which are acids can be nuetrolised and this prevents tooth decay.thanks sir
Sir,your teaching is very good.
KEEP IT UP!
Is it that universal indicator better?
Please answer as I have a science test
1.HNO3+ NH4OH - NH4NO3+H2O
2.a) acetic acid b) Lactic acid
c) Oxalic acid d) malic acid
3. Bacteria present in our mouth may react with sugar and generate acids.This can corrode our tooth enamel which leads to tooth decay. Toothpastes which are basic in nature can neutralize these acids and thus can prevent our tooth from decaying.😅
Toothpaste helps prevent tooth decay through its active ingredients, which work in several ways:
1. Fluoride: Most toothpaste contains fluoride, a mineral that strengthens tooth enamel, making it more resistant to acids produced by bacteria in the mouth. Fluoride also helps remineralize areas where enamel has started to break down, reversing early signs of decay.
2. Antibacterial agents: Toothpaste often contains compounds like triclosan or stannous fluoride that help reduce the number of harmful bacteria in the mouth. These bacteria contribute to plaque formation and acid production, both of which lead to tooth decay.
3. Physical Abrasives: The mild abrasives in toothpaste help scrub away plaque and food particles from teeth, reducing the potential for bacteria to grow and cause cavities.
4. Prevents Acid Erosion: Toothpaste helps neutralize acids produced by bacteria in the mouth, which can erode enamel and lead to cavities.
By brushing with toothpaste regularly, you help protect your teeth from the factors that cause decay.
Thanks for inspiring many different children about science, great job
It's my pleasure
Really nice video.. The most effective thing in the video is that you have performed the things practically rather than a neat display which is very very helpful... Really nice
Thanks a ton
Excellent Sir !! Practical teaching is really good
Q2) Answer - (a) Acetic Acid , (b) Lactic Acid , (c) Citric Acid, (d) Malic Acid
Q3) Answer - when we are not brushing our teeth the microorganisms starts feeding on the remains or which is stuck between our teeth and they start producing acid this acid which is produced from microorganisms will lead to the teeth decay, so to neutralise the acid, we have to use base (toothpaste)
Q1:HNO3+NH4OH=NH4NO3+H20
Q2: Vinegar: oxalic acid and acetic acid
Milk:Lactic acid
Tomatoes:Malic acid, oxalic acid,citric acid ascorbic acid
Apples:Malic acid and tataric acid
Q3: Toothpastes defend the tooth from teeth decay because it contains fluoride which is a weak base and neutralizes the effects of the bacteria in the mouth which is acidic
Sir u teach very well you should be a VIP teacher in online classes.
Thanks
Sir,Tomorrow I have exam for the chapter ACIDS BASES AND SALTS and this video was very helpful.
May u live for 100+ years and enrich students like us
Me2 gaving kalai neenga enga school

Today exam
My name also Kalai
Oo
1)NH4OH + HNO3 = Ammonium nitrate + H2O
2)a. Acetic acid
b.Lactic acid
c.Oxalic acid
d.Malic acid
3)The covering of the teeth is enamel which is a base. The cavities are acidic in nature. So, it will corrode the enamel layer
giving us some teeth sensitivity. So, it is better you brush your teeth with toothpaste because toothpaste is basic helping the enamel and prevent corroding.
Actually,we eat the food which contains acids and if the acidic nature is more in our teeth it may cause tooth decay so we use the basic paste to neutrilize it
Super sir best website Manocha academy for cbse students .. sir
