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.
@@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 🤣😂🤣😂🤣😂🤣
Cbse ***** hai to kya kare bhai? Pandemic main practcials karane ka kya matlub hai? Pagal jaisa kar rha hai. Aadmi padhai likhai kare ya fir baikati ? Kya cbse nahi jaanta majority of the places main january tak school nahi khule hai? Abhi v mumbai and kucu states main corona high hai
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
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
@@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.
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
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.
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.
@@theflea2539 hum log poora observation ratt ke gye , salt analysis ka kuch ppt nikal he ni rha tha 😂😂 aur kmno4 wale alag alag reading aati teeno baar
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.
Thank you maam..we don't have good teachers to explain all these in lab so we wait for your videos ..your explanation was wonderful thank you so much♥️
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 ❤🙏
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.
@@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
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
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😊❤️
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 so much mam, my school is in containment zone thus I am unable to go to school for practical and you solve this problem. God gives you each and every thing what you want
Maam we always miss the education quality 😔😔 ... but thanks maam its so helpful to the guys like me .... well it will help to many of my mate's friends.... on behalf of each of them I wanna thank u ma'am.... 🙏🙏🙏
Seema Ma'am tomorrow is my chemistry practical examination for term 1 i.e. Volumetric + Salt Analysis I am watching your video for the revision of my practical classes. Really enjoyed watching your videos and learning from them as well
Bahut accha explain kiya mam aapnay saara titration samaj aagaya mujhay aise hi videos banaatay rahiye mam thank u so much for this wonderful video 😁😁👌
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! 😊😊
Very good demonstration of titration experiment. However, with due respect I would like to point out a few things: 1. We should check whether the burette and pipette are properly clean or not. This can be checked very easily by seeing that no water droplets stick on the inner wall of the burette and the pipette after rinsing with distilled water. 2. It should be told how to read burette reading in case of coloured and colorless liquids i. e. lower meniscus or upper meniscus. 3. The pipette should not be kept on the table surface after use because the dust/chemical on the table may contaminate the pipette and when the same pipette is used again and dip into the soluion it may contaminate the whole solution (reagent ).
Agree! Great explanation nonetheless. You can check out Bhatia mam's video on the same experiment where she has also explained how to take readings. For your convenience, time stamp at 5:38 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-SE_Ar71nqFY.html
