Sir, if we take samples of natural gum rosin from different portions of the same drum, is there any possibility that tge acid value get varies by 4 digits?
sir ur teaching is really amazing. thanku for such videos. sir plz provide notes on utube itself, coz on the link provided by u the notes r not available.
to estimate the amount of titrant that would react with the pure solvent. In this way, we can estimate the error that can be produced when the actual titration done
Dissolve about 5.61 g of potassium hydroxide in 5 ml of water+ Add sufficient aldehyde-free ethanol (95 %) to produce 1000 ml. Allow the solution to stand for 24 hours.
sir hum saponification me bhi KOH ka use karte hai . to agar oil renicid bhi hua to bhi acid to produce hoga hi aur KOH to usse bhi react karega aur bad me jo bacha hua oil usse bhi acid alag karke react karega to saponification value to humesa jada hi ayegi..
Dr. Parjanya Shukla & Dr. M. P. Singh Classes then sir how we identify by saponification value that the oil is good or bad if saponification value always more
Dr. Parjanya Shukla & Dr. M. P. Singh Classes whether the oil is renicid or not KOH will react all acid whether it is present in free state or in combine form. saponification value will always more
@@anuragvishwakarma6693 simply you can check acid value first. That will give the idea about rancidity. If oil is good then go for saponification value
Thanku so Much sir wonderful Lecture
Keep uploading the next topics sir this was very helpful for us 👍👍👍👍🙏🙏
Thanks. Keep watching and share to needful students
Thanku so Much sir u explain this Topic very clearly.
Dr Shukla Love from Pashtonkhwa
Best explanation sir
Keep watching and Share to needful students
Sir ur content is awesome
Thanks Dear. Keep watching and share to needful students
Tq so much sir etna easy notes provide krane ke liye🙏🏻🙏🏻🙏🏻
Sir how to reduce high acid value ?
Thanks sir
Nicely explained
🙏
Saponification value , a and b value hcl ke liye hoga ya koH ?
Thanks for all
Sir exam may aayga too procedure bhi likhna hai
Thank uh so much sir🙏
Your welcome Dear keep watching
How you prepared 0.5N alcoholic KOH
Thank u sir ..
Explanation ❤️
Sir... In saponification value... We are titrating with HCL not with KOH no.... So how can B is volume of KOH?.....
Go through the Topic Again dear , before titration with HCl we reflux the sample with alcoholic KOH and titration is done to trace remaining KOH
Plz explain iodine value briefly
Tnx bhai ji

Sir acid value and other values m itna exam m likhna sufficient hai??

Ohh, find it on telegram
Sir organic k liye konsi book best h
Go for any book you love to read
Ok sir

sir, please help me if the acid value of the used cooking oil is high then how can you reduce it
Acid value is used to check only quality of oil. It can't be reduced
Why we have to do blank titration??
to estimate the amount of titrant that would react with the pure solvent. In this way, we can estimate the error that can be produced when the actual titration done

How to prepare 0.1N alcoholic KOH solution
Dissolve about 5.61 g of potassium hydroxide in 5 ml of water+ Add sufficient aldehyde-free ethanol (95 %) to produce 1000 ml. Allow the solution to stand for 24 hours.
Can we test acid value with Naoh and what will be difrence in between acid value by naoh and koh
can use NaOH in place of KOH. Just change molecular wt of KOH to NaOH in formula
sir hum saponification me bhi KOH ka use karte hai . to agar oil renicid bhi hua to bhi acid to produce hoga hi aur KOH to usse bhi react karega aur bad me jo bacha hua oil usse bhi acid alag karke react karega to saponification value to humesa jada hi ayegi..
Yes if oil is rancid. It is possible
Dr. Parjanya Shukla & Dr. M. P. Singh Classes then sir how we identify by saponification value that the oil is good or bad if saponification value always more
Dr. Parjanya Shukla & Dr. M. P. Singh Classes whether the oil is renicid or not KOH will react all acid whether it is present in free state or in combine form.
saponification value will always more
@@anuragvishwakarma6693 simply you can check acid value first. That will give the idea about rancidity. If oil is good then go for saponification value
Dr. Parjanya Shukla & Dr. M. P. Singh Classes thanks sir,
it means we can't determine by saponification value that whether the oil is ranicid or not .
How much reading you got for blank titration
That the formula only, you have to conduct titration to get value
Not like that sir
If you have taken 0.5 N KOH 25 ml
Then how much was your reading?
Can you please tell how to make alcoholic KOH solution?
Dissolve 2.8 g. KOH in a mixture of equal volumes of ethanol and doubly distilled water, and make up to 100 ml. It will 0.5 N solution
@@parjanya24 ethanol ke jagah par methanol use kar sakte he kya.?
If not available then
SAP value me 0.5 N HCL aayega calculation me
O.5n HCl use why?

Please joo bhi unlike karta hai woo vidio ko mat dekhe apke unlike karne se kuch nahi hota
Sir acid value me 5.61 hoga formula me
Check the formula if we divide 56.1 to 10. Actually the 56 is the value of molecular wt of KOH
Ester value ka procedure nahi hai sir
Simple process hai
@@parjanya24 oky sir
Gtu na imp question apo ne
Sir I have a question
Ji bataiye
@@parjanya24 saponification kya h
Aur Q krte h chemical testing iski????
Simply to check the industrial application of oil and also Just to check quality of the oil.
Thank you sir
Sir , how to reduce acid value ?
