Some Basic Concepts of Chemistry - Result Question 14

14. The reaction, $3 ClO^{-}(a q) \longrightarrow ClO _3^{-}(a q)+2 Cl^{-}(a q)$ is an example of

(2001)

(a) oxidation reaction

(b) reduction reaction

(c) disproportionation reaction

(d) decomposition reaction

Show Answer

Answer:

Correct Answer: 14. (c)

Solution:

It is an example of disproportionation reaction because the same species $\left(\mathrm{ClO}^{-}\right)$is being oxidised to $\mathrm{ClO}_3^{-}$as well as reduced to $\mathrm{Cl}^{-}$.
