1. why the potassium manganate has to be acidified before performing the titration between potassium manganate and ethanedioic acid (oxalate acid)?
2. why does sulphuric acid is used instead of hydrocloric acid in Question 1?

1) It is acidified because in neutral or basic conditions it disproprotionates to give manganese dioxide and potassium permanganate.
2) HCl is not used because potassium manganate oxidises it to chlorine.
