In my school, knob of burettes have a mind of their own.
In mine school too🤣🤣🤣....... kal prac. hai darr hai ki kuch ulta sidha rxn ho gya toh pura lab udd jaayega 😂😂😂😂
Those knobs really do not like me. They'll do anything to piss me off 😂😂
@@yashrajkhopade Thik gya bro .....Shuru me Video ka jitna yaad tha utna kiya ........uske baad toh puri class koi bhi Chemical utha ke daal rhi thi beaker 😂🤣😂🤣😂🤣😂😂.........ITS LIKE WE ARE PLANNING TO OPEN A PANI PURI STALL 🤣😂🤣😂🤣😂🤣
@@sarvagya-3195 kal mera practical h🤦
@@sarvagya-3195 lab ke saath gaand bhi ud jayega
For things to get more simple.I hope this will help :)
1)Wash Burette
2)Rinse with KMnO4
4)Fill KMnO4 upto a reading of 13.5
5)Clamp it up
6)Wash conical flask (or titration flask) with only water
7)Have a 10ml Pipette (Wash-Water only,by simply sucking some water through it)
8)We need to use the Pipette to measure the oxalic acid.
(get it from measuring flask to beaker)
9)Take 10ml of oxalic acid.(Just get the right level by use of your finger)
10)Add it in the water washed Titration flask.
11)Need 1 test tube (almost full) Of dil.H2So4 for the titration
(as an acidic medium is needed)
12)Add it to the beaker of oxalic acid .
13)Since the reaction is slow we require to heat. WE NEED(60-70)°C to start the titration.
14)To know the right temp. by just observing we can do 1 thing,
once the inner edges of flask developes some droplets NOTE THAT IT'S YOUR TIME TO START THE TITRATION PRACTICAL
~#DO NOT HEAT IT TO THE BOILING TEMP.#~
15)INITIAL ADDITION SHOULD BE DROPS WISE later u can add splashes of it.
reason: INITIALLY Mn2+ needs to be formed which works as an autocatalyst in this expm.
16)Do this till you get a lightest possible pink.
Thank you bhai very helpful
@@bhavishya6030 Welcome🙂
Fill kmno4 upto reading 0.It will be really helpful in calculations.
@@whydoyoucare537 Yeah
When i did it in my school, my teacher also suggested this.
it's not important to fill till 13.5
Anyone for Term 1 OR Term 2 practical exams which one you preparing for?😊
:)
@Itachi Uchiha DONT TAKE ANY TENSION BRO MERA BHI BHUT BDIYA GAYA HAI
@Itachi Uchiha AND AAGAR MAAM ITNI BHI STRICT NA HO TO TO BOL DENA MAAM 1AND 2 ND CHAPTER SE PUCHLO PLEASE MERE SATH BHI YHI HUA

Well is 5 am and my exam is on 11 am
Damn I thought I was the only one😂😂😂😂😂
Oooo I Am A Legend
From her way of speaking only I can say she is one of the strictest teachers...😭✌
Even my chemistry teacher talks like that while explaining stuff but tbh she an absolute sweetheart 🤣
Mujhe bhi vahi laga 😭
For your kind information plz on your subtitles and see what is happening in video
bro I am her student and she is one of the sweetest teachers , don't judge maam
such teachers who don't promote their channel anytime during the entire video and nly give us best wishes deserve huge respect and affection frm all the students watching their video

Bhai...practical ke 2 ghante pehle hi dekh raha hu
I'm watching this a day before final practical
find out the percentage purity of impure sample of oxalic acid you are supplied m/100 kmno4 solution
She is kind of teacher we need on online platform rather than those thirst trap teachers who just showcases their so called beauty in front of their students NGL
Everybody uploads the lectures but not practicals,thanks a lot mam❤️
we need teacherss like you in our practical labs !!! thank you so muchh !!
Yes...
And I also love listening music😁😁
I love you

thank you maam, this was really helpful as I cannot go to school for thr practicals but now have to give the final practicals of boards. Keep Uploading maam , complete the series of class 12th
Check the playlist for 12 practicals on my channel .you will find all practical videos
@Richa Priya yes. In our school also we add dil sulphuric in both
@@seemamakhijani721 , dear ma'am, for 2023 exams, are we supposed to do all experiments as given in the curriculum? I can see several new experiments have been added.
being in lockdown could not atttend practical classes, but i understood it pretty well from you, thank you maam
Thanks
You are really lucky one my friend didn't have to go through this
Whole comment section be like:
Who is here for term 1
Legends are watching 1 day before exam
Ultra legends are watching in school corridor
The way you handles the glass instruments makes me fell it's going to crack ( worst possible, shatter into pieces) but it doesn't and makes you look more professional.
Thank you maam, videos like these are very helpful for students like me who are not able to do practices but just note it on note book (imaginings the process in head) which makes us feel chamestry boring.
Your videos are very helpful and always will be to the up coming students of Xll and others who needs it. Thank you again.
Thank you very much, ma'am, for these videos. These videos are so very helpful to us, especially in this post-COVID situation, where schools are just rushing with practicals ( like completing 2/3 experiments in a single lecture ) in order to wrap up as soon as possible.
tommrow will be my pratical exam😂
I am going to school now and watching it in the car 😂
tomorrow is my practical exam and now i am binge watching all practical videos. Thank you ma'am for saving us.
same
Thank you for these precious videos and tips ! It really helps to boost confidence before practical exams!
Thank you !!
Ma'am aapko jitna thanks bolu Kam hai bcz the way u made each thing crystal clear was something that my chem teacher could never make me understand. MTLb I swear aap itne calm voice mein smjhate ho na ki ... MTLb I can't just explain in words but fr ma'am ur an angel and I wish u help people like us forever nd may God send more angels like u to the earth...❤
ma'am thank you so much, it's so awful that my school never took us to lab more than 2-3 times, and we are expected to do these kinds of experiments tomorrow in practical, thank you so much ma'am, more practical teachers need to exist.
I understood how to do titrations really well. Thank you, ma'am. Hope you are having a great day.
Thank you mam ,my teacher not taught us and asked to do the practical
By God grace I had seen your video and I proceeded further 😭😭thanks mam ,ye khushi ke aaaashu hain
Thank you ma'am for making such practical videos
Very clear and easy to remember explanation !! Thank you so much mam 😀😀
What required my teacher to explain in 2 hrs, you have explained it within 8mins and surprisingly even better. Hats off to you ma'am
Thank you for your efforts.
exactly shes awesome dude
You found this 8 minutes better because of that 2 hrs explanation 😅🙂
@@lakshya_13 @Laksh Lokhande doubt- first reading was 13.5 and next time when she remove some kmno4 (pink liquid) how 33 is available answer fast practical is after 2 days
Ma'am I already shared it to my friends(without seening the whole video).. When I just heard ur english at that point I came to know this teacher is the best for our final practicals.
Thanq ma'am ❤🙏
Thank you ma'am for this video....... It helps me a lot for my practical examination 😊😊

So beautifully explained there is no language to say. I hope to get such a video ahead.
Mam is chemistry legend
Video I need. perfect

Ma'am very helpful no words to express my gratitude for your work
Actually the endpoint is supposed to be lighter than this..but I loved your video and noted down the little pointers for a correct experiment which I was never told about..thank you so much ma'am
Thank you so much for this video Ma’am! I have my board practical examination tomorrow and I’ve never performed titration of KMnO4 with Oxalic Acid, but Mohr’s salt solution. This video helped me a lot; now I can perform this experiment easily in tomorrow’s examination. We need more teachers like you, well explained😊❤️
Bro same I've my chem exam tomm too 😅
@@sucks9974 Hahaha, all the best bro👍🏻
@@Trishaaa all the best to you too
Actually I was absent for oxalic one and did the Mohr but for tomm I've to perform the oxalic one
Btw from where are you
@@sucks9974Same here lol. I've done the Mohr's salt one before but not oxalic acid one. I’m from Northern part of India. You?
What a nice explanation of practic.... Thanks a lot.....
This video made everything clear about titration thank you ma'am
I have my practical a couple of hours later. Thank you ma'am 🙏
thank you soo much mam I was literally able to perform in lab without practice...
A very good morning respected mam
Protocol of burette is to wash it with water
Roll and wash it into sink
Up and down clean closer
Rinse by KMnO4 to avoid the conc. to change
Fill burette upto the eye level
Check the reading 13.5
Press the clamp , shift and fix burette
Conical flask or titration flask
Protocol wash
Pipette
Wash, Suck upto cut point (it may take some time...loosening the tension or inc again)
From conical flask to beaker
Pippette to water wash beaker
Bottom surface twice touch with pippete
Acidic medium 1 test tube full Sulphuric acid
Heat 60°C
Inner edges develop water flasks neck...
Few drops more drops until it no more dissolves.
Reading
Concordant reading
Thank you mam I am watching this before my practical
Miss thank you very much we need teacher like you in chemistry labb

Same mine is tomorrow and I'm daring to watch it today😂😂😂🤣
How did it go?
Never using pipette by mouth. It is very risky.
Please follow the GLP rules...
Thanks for the video🏃🏿♀️
Thank you mam you demonstrated it very well
My boards practical is tomorrow that's why I am watching this video today 🤣

Mam this was good explanation thank you for explaining nicely
I got Oxalic acid titration in today's practical, it was all thanks to you I was able to do it easily.
And I'm kinda relieved that it went great.
Once again, thankyou for teaching correct procedure and questions! 😊😊
When you were absent at the day of the practicals and now you're smart enough to predict that "practical exam me lagni h tmhri"🙌😁gl
