Chapter 4, Problem 4.81QP

(a)

Interpretation Introduction

Interpretation:

The given reaction has to be classified based on its type.

Concept introduction:

Redox reaction:

  • The chemical reaction in which, oxidation reaction and reduction reaction always occurs together and are called  oxidation reduction reaction, abbreviated as redox reaction.
  • Disproportion reaction is the special type of reaction where an element in one oxidation state is simultaneously oxidised and reduced.

Acid -Base reaction:

  • The reaction between acid and base to produce a salt is called acid-base reaction.

Precipitation reaction:

  • If precipitate is formed, when the two solutions are mixed together is called precipitation reaction.

Combination reaction:

  • In the reaction, there is no change in oxidation numbers of atoms present in the reactants and products is and only the product is offered by the combination of reactants is called combination reaction.

Explanation of Solution

Given reaction is

Cl2+2OH-Cl-+ClO-+H2O

On the left side, the oxidation number of chlorine in Cl2 is zero and on the right side the oxidation number of Cl is 1 , which means chlorine is reduced. In ClO-, oxidation number is +2 and is oxidized in the given reaction. So the given reaction is a disproportionation redox reaction.
