Oxidation is defined as:
Correct answer: D. Both a and c
- A. Loss of electron
- B. Gain of electron
- C. Gain of oxygen
- D. Both a and c
Explanation
Oxidation can be defined in two ways:1. Loss of electron(s): This is the modern definition in terms of election transfer.2. Gain of oxygen: This is an older definition based on the reaction with oxygen.Therefore, both (a) and (c) are correct descriptions of oxidation.

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.
