The reaction Cl(2)(g)+20H^(-)(aq)toClO^(...

The reaction `Cl_(2)(g)+20H^(-)(aq)toClO^(-)(aq)+Cl^(-)(aq)+H_(2)O(l)` represents the process of bleaching. Identify and name the species that bleaches the substances due to its oxidising action.

Text Solution

Verified by Experts

Writing the O.N of each element above its symbol we have
`CI_(2)(g)+2OH^(-)(aq)rarrCIO^(-)+CI^(-)(q)+H_(2)O^(-)(l)`
in this reaction O.N of CI increase from 0 in `CI_(2)` to + 1 in `CIO^(-)` therefore is both oxidised to `CIO^(-)` and reduced to `CI^(-)` since `CI^(-)` ion cannot act as an oxdising agent therefore `CI_(2)` bleaches substances due to to oxidising action of `CIO^(-)` ion
