The reaction: Cl2 + H2O → HCl + HOCl is an example of:
Correct answer: C. Auto-oxidation and reduction reaction
- A. Oxidation reaction
- B. Reduction reaction
- C. Auto-oxidation and reduction reaction
- D. Substitution reaction
- E. Addition reaction
Explanation
Auto-oxidation and reduction reaction is a reaction in which the same element is oxidized as well as reduced. In the reaction given above, the Cl element reduces to Cl-(HCl) and oxidizes to Cl+(in HOCl).

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.
