    Ma'am, you could have shown the entire process of the solution turning pink( you just showed a bit and edited the rest) because that's where most of the focus needs to be since an extra droplet of KMnO4 can give wrong readings and colour, also the colour should be very light pink, whereas the pink that you have obtained is quite dark. But nonetheless, well explained. Thank you, ma'am

Lab assistant apko practical karte hue notice karega. Humara luck acha tha ki lab assistant nahi aaya. Bas chair pe examiner tha. aapke class teacher bata denge ki apko konsa wala practical milega aur konsa question milega. Bas acha behaviour rakho school teacher se. Baaki sab normal hai , teacher apko phele hi bata denge ki titration ke solution ki kya reading hai uske hisab se apni reading yaad rakhna. Titration me galat reading bhi aaye toh wahi reading likhna paper pe ko teacher ne batayi

Mam, I am suffering from colour blindness from an early age, will my defect result in not getting accurate answers in both titration and also flame test(confirmation of Ca2+ and ba2+). . Mam,Will this affect my practical marks? Mam,if I get a slight different final answer for titration due to my problem..will they give me marks or cut short my practical marks?

      It depends on molarity of oxalic acid you want and the volume you've taken.
      0.63 gram for m/20 solution of 250 ml

      If you wash only with water then dilution will occur and there will be change in concentration .So same solution se rinse kerna chahye burette ko.
