Question

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

• A. $PbS +4 H _2 O _2 \rightarrow PbSO _4+4 H _2 O$
• B. $2 Fe ^{2+}+ H _2 O _2 \rightarrow 2 Fe ^{3+}+2 OH ^{-}$
• C. $HOCl + H _2 O _2 \rightarrow H _3 O ^{+}+ Cl ^{-}+ O _2$
• D. $Mn ^{2+}+ H _2 O _2 \rightarrow Mn ^{4+}+2 OH ^{-}$

Answer 1
