KMnO4 Vs Oxalic acid Titration class 12 by Seema Makhijani Chemistry Practicals PROCEDURE.

[@Rashmi07]

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.

[@prabhatnigam9407]

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 ).

[@mannatb7504]

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 kzbin.info/www/bejne/iXbCcqVtZtOkfLs
