NEET Chemistry Balancing Redox Reactions MCQ Question
Type: MCQ-conceptual-Easy-Class 11
Which of the following combinations correctly identifies the species undergoing oxidation and reduction in the provided redox reactions?
A
(i) H2S is oxidized; Cl2 is reduced. (ii) Al is oxidized; Fe3O4 is reduced.
B
(i) H2S is reduced; Cl2 is oxidized. (ii) Al is reduced; Fe3O4 is oxidized.
C
(ii) Al is reduced; Fe3O4 is oxidized. (iii) Na is reduced; H2 is oxidized.
D
(i) Cl2 is oxidized; H2S is reduced. (iii) H2 is oxidized; Na is reduced.
Correct Answer
Option A
Detailed Explanation
In reaction (i), H2S loses electrons (oxidation) while Cl2 gains electrons (reduction). In reaction (ii), Al is oxidized by gaining oxygen, and Fe3O4 is reduced as it loses oxygen.
