Question

In volumetric analysis what is colour of end point

Answer 1

Explanation:

A potentiometer or a redox indicator  is usually used to determine the 'endoint' of the titration , as when one of the  constituents is the oxidizing agent  potassium  dichromate .

The color change of the solution from orange to green is  not definite, therefore an indicatore such as sodium  diphenylamine is used.
