MCQ

In which of the following reactions ${H_2}{O_2}$ is a reducing agent

A
$2FeC{l_2} + 2HCl + {H_2}{O_2}\, \to \,2FeC{l_3} + 2{H_2}O$
✓
$C{l_2} + {H_2}{O_2}\,\, \to \,\,2HCl + {O_2}$
C
$2HI + {H_2}{O_2}\, \to \,\,2{H_2}O + {I_2}$
D
${H_2}S{O_3} + {H_2}{O_2}\, \to \,\,{H_2}S{O_4} + {H_2}O$

Answer

Correct option: B.

$C{l_2} + {H_2}{O_2}\,\, \to \,\,2HCl + {O_2}$

(b) $C\mathop {{l_2}}\limits^o + {H_2}{O_2} \to \mathop {2HCl}\limits^{\,\,\,\,\,\,\,\,\, - 1} + {O_2}$. In this reaction chlorine reduced from zero to $-1$ oxidation state.
