Question
Complete the following chemical reaction.
\[\ce{MnO^-_{4(aq)} + H_2O_{(g)} ->}\]
Classify the chemical reaction into (a) hydrolysis, (b) redox and (c) hydration reactions.
Solution
\[\ce{2MnO-_{4(aq)} + 5H_2O_{2(g)} -> 6H^+_{(aq)} -> 2Mn^{2+}_{(aq)} + 8H_2O_{(l)} + 5O_{2(g)}}\]
`"H"_2"O"_(2("aq"))` is acting as a reducing agent in the acidic medium, thereby oxidizing `"MnO"_(4("aq"))^(-)`
Hence, the given reaction is a redox reaction.
