The reaction, 3ClO⁻(aq)→ ClO₃⁻(aq)+ 2Cl⁻(aq) is an example of:
Correct answer: C. Disproportionation reaction
- A. Oxidation reaction
- B. Reduction reaction
- C. Disproportionation reaction
- D. Decomposition reaction
Explanation
This is a disproportionation reaction because the same element, chlorine, is simultaneously oxidized and reduced. The oxidation state of Cl in ClO⁻ is +1. It is oxidized to +5 in ClO₃⁻ and reduced to -1 in Cl⁻.

About Electrochemistry
Electrochemistry describes electron transfer through oxidation and reduction, identifies oxidizing and reducing agents, and applies oxidation numbers to balance redox equations. It also covers electrode potential and the standard hydrogen electrode, which provides the reference for comparing the reduction tendencies of other electrodes.
