Cannizzaro reaction is an example of

When $Cl_2$ gas reacts with hot and concentrated sodium hydroxide solution,the oxidation number of chlorine changes from

What sorts of information can you draw from the following reaction?
$(CN)_{2}(g) + 2OH^{-}(aq) \rightarrow CN^{-}(aq) + CNO^{-}(aq) + H_{2}O(l)$

What change occurs in the oxidation state during a disproportionation reaction?

The reaction $Cl_2 + 2OH^{-} \to ClO^{-} + Cl^{-} + H_2O$ represents the process of bleaching. Identify and name the species that bleaches the substances due to its oxidising action.

Which ion undergoes disproportionation in an aqueous solution?
