What products are expected from the disproportionation reaction of hypochlorous acid?

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.

Identify the oxidation states of $Mn$ when $MnO_4^{2-}$ ion undergoes disproportionation reaction under acidic medium.

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

$3ClO_{(aq)}^{-} \to ClO_{3(aq)}^{-} + 2Cl_{(aq)}^{-}$ : This reaction is an example of what?

Which of the following acts as both an oxidizing and a reducing agent?
