For the reactions of 1 mol of H2O2, select the correct statement(s).

With acidified KMnO4 it acts as a reductant and releases 1 mol O2

With acidified KI it acts as an oxidant and liberates 1 mol I2

It consumes 0.4 mol of KMnO4 in acidic medium

With acidified KMnO4 it acts as a reductant and releases 1 mol O2

With acidified KI it acts as an oxidant and liberates 1 mol I2

It consumes 0.4 mol of KMnO4 in acidic medium

Its n-factor in 2H2O2 -> 2H2O + O2 is 2

For the reactions of $1$ mol of $H X_{2} O X_{2}$ , select the correct statement(s).

AWith acidified $KMnO X_{4}$ it acts as a reductant and releases $1$ mol $O X_{2}$
BWith acidified $KI$ it acts as an oxidant and liberates $1$ mol $I X_{2}$
CIt consumes $0.4$ mol of $KMnO X_{4}$ in acidic medium
DIts $n$ -factor in $2 H X_{2} O X_{2} 2 H X_{2} O + O X_{2}$ is $2$

H X_{2} O X_{2} O X_{2} + 2 H X^{+} + 2 e X^{-}

, so A is true; moles

KMnO X_{4} = 2/5 = 0.4

, so C is true.

H X_{2} O X_{2} + 2 I X^{-} + 2 H X^{+} I X_{2} + 2 H X_{2} O

gives

1

mol

I X_{2}

, so B is true. In the disproportionation 2 mol

H X_{2} O X_{2}

exchange 2 electrons, so

n = 1

per

H X_{2} O X_{2}

, making D false.
