The reaction
`3ClO^(ө)(aq)rarrClO_(3)(aq)+2Cl^(ө)(aq)`
is an example of

Options

A. Oxidation reaction
B. Reduction reaction
C. disproportionation reaction
D. decomposition reaction

Answer

C

Explanation

O.N of Cl in `ClO^(-),ClO_(3)^(-) and Cl^(-)` ions are `+1, +5 and -1` respectively. Therefore, O.N of Cl increases from +1 (in `ClO^(-)` ions) to +5 (in `ClO^(-)` ion) and also decreases from +1 (in `ClO^(-)` ion) to -1 (in `Cl^(-)` ion). Therefore, it is a disproportionation reaction.
