• # question_answer In which of the following reactions, ${{H}_{2}}{{O}_{2}}$ acts as a reducing agent [EAMCET 2001] A) $Pb{{O}_{2}}(s)+{{H}_{2}}{{O}_{2}}(aq)\to PbO(s)+{{H}_{2}}O(l)+{{O}_{2}}(g)$ B) $N{{a}_{2}}S{{O}_{3}}(aq)+{{H}_{2}}{{O}_{2}}(aq)\to N{{a}_{2}}S{{O}_{4}}(aq)+{{H}_{2}}O(l)$ C) $2Kl(aq)+{{H}_{2}}{{O}_{2}}(aq)\to 2KOH(aq)+{{I}_{2}}(s)$ D) $KN{{O}_{2}}(aq)+{{H}_{2}}{{O}_{2}}(aq)\to KN{{O}_{3}}(aq)+{{H}_{2}}O(l)$

In the following reaction ${{H}_{2}}{{O}_{2}}$ acts as a reducing agent. $Pb{{O}_{2}}(s)+{{H}_{2}}{{O}_{2}}(aq)\to PbO(s)+{{H}_{2}}O(l)+{{O}_{2}}(g)$
