Reducing nature of H2O2 means it reduces other substance and itself gets oxidised by evolving O2 . In (a), Mn+ 7 gets oxidised to Mn+ 3 . In (b), I2 gets reduced to I- . In (c), Mn2 + gets oxidised to Mn4 + In (d), Pb+ 6 gets oxidised to Pb2 +

Q. Which of the following equation depict the reducing nature of $H_{2} O_{2} ?$

$2 M n O_{4}^{-} + 6 H^{+} + 5 H_{2} O_{2} \to 2 M n^{+ 2} + 8 H_{2} O + 5 O_{2}$

$I_{2} + H_{2} O_{2} + 2 O H^{-} \to 2 I^{-} + 2 H_{2} O + O_{2}$

$M n^{+ 2} + H_{2} O_{2} \to M n^{+ 4} + 2 O H^{-}$

$P b s + 4 H_{2} O_{2} \to P b S O_{4} + 4 H_{2} O$
