Correct answer is (c) HOCl + H 2 O 2 arrow H 3 O ++ Cl -+ O 2

Q. In which of the following reactions the hydrogen peroxide acts as a reducing agent?

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

$2 F e^{2 +} + H_{2} O_{2} \to 2 F e^{3 +} + 2 O H^{-}$

$H OCl + H_{2} O_{2} \to H_{3} O^{+} + C l^{-} + O_{2}$

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

Correct answer is (c) $H OCl + H_{2} O_{2} \to H_{3} O^{+} + C l^{-} + O_{2}$

Q. In which of the following reactions the hydrogen peroxide acts as a reducing agent?

PbS+4H2​O2​→PbSO4​+4H2​O

2Fe2++H2​O2​→2Fe3++2OH−

HOCl+H2​O2​→H3​O++Cl−+O2​

Mn2++H2​O2​→Mn4++2OH−

Correct answer is (c) HOCl+H2​O2​→H3​O++Cl−+O2​
