Which of the following reactions is divided into two parts?
Correct answer: B. Redox reaction
- A. Oxidation
- B. Redox reaction
- C. Reduction
- D. None of these
Explanation
A redox reaction consists of two parts; an oxidation half-reaction and a reduction half-reaction that always occur together. A chemical species loses electrons in the oxidation half-reaction while a chemical species gains these electrons in the reduction half-reaction.

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.
