Question

Make a project about titration of KMnO4 with standard solution of oxalic acid.​

Answer 1

Explanation:

The molarity of potassium permanganate can be found by titration of KMnO4 with standard solution of oxalic acid.​

Appratus Needed

Burette

Burette stand

Pipette

Conical flask

Lab Funnel

Measuring flask

Standarised solutions of oxalic acid and KMnO4

Procedure

Take 2 g of oxalic acid and max it in 500ml of water. Now take 20ml of this solution and pour it in a titration flask. Fill the burette with KMn04 and note the initial reading

Now add one test tube of sulphuric acid to that titration flask. The flask is heated KnM04 is added in the flask till a pink colour starts to appear in the flask. Note the final reading in the burette.

Carry out calculation to determine molarity of KMn04
