Question

The products obtained from a reaction of hydrogen peroxide and acidified potassium permanganate are

• A. $Mn^{4+}, H_2O \;only$
• B. $Mn^{2+}, H_2O \;only$
• C. $Mn^{4+}, H_2O, O_2 \;only$
• D. $Mn^{2+}, H_2O, O_2 \;only$

Answer 1

Answer: (D)

$Mn^{2+}, H_2O, O_2 \;only$

Answer 2

$2MnO^-_4−+6H^++5H_2O_2 → 2Mn^{2+}+8H_2O+5O_2$

This reaction shows reducing action of $H_2O_2$ in acidic medium.

The products formed are $Mn^{2+}$, $H_2O$ and $O_2$.
