Question

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

Answer 1

Answer:

Sulphuric Acid (H2SO4) is used in the redox titration process because it provides the H(+) ions necessary for the reaction to occur more quickly whilst the sulphate(-) ions barely react during the reaction. ... Therefore, sulfuric acid is added to make the solution acidic.
