Question

Why is dilute H2SO4 added in KMnO4 titrations instead of HCl or HBr and HNO3 and HNO3?

Answer 1

Explanation:

Dilute H2SO4 is used in KMnO4 titration beacuse H2SO4 is strong acid which gives H+ ions readily ,and potassium permaganate shows it's indicator effect in acidic medium by changing it's colour from purple to colour less and therefore reaction proceed in forward direction and in a stable way.
