Question:
Which of the following phenomena represents oxidation?
Which of the following phenomena represents oxidation?
Show Hint
Oxidation is addition of oxygen or an electronegative element, or removal of hydrogen or electropositive element.
Updated On: Oct 1, 2026
- Removal of oxygen
- Addition of electronegative element
- Addition of electropositive element
- Gain of electron
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Recall the classical definition
Oxidation is the addition of oxygen or any electronegative element to a substance, or the removal of hydrogen or an electropositive element from it.
Step 2: Check the options
(A) Removal of oxygen is reduction. (B) Addition of an electronegative element is oxidation, for example \(Mg + Cl_2 \rightarrow MgCl_2\). (C) Addition of an electropositive element is reduction. (D) Gain of electrons is reduction, in the electronic concept.
Final Answer:
Addition of an electronegative element is oxidation. \[ \boxed{\text{(B)}\ \text{Addition of electronegative element}} \]
