NEET Chemistry (general) MCQ Question
Type: MCQ-numerical-Easy-Class 11
In the redox reaction where sodium metal reacts with hydrogen ions to form sodium ions and hydrogen gas, which of the following correctly represents the oxidation half-reaction?
A
2 Na (s) → 2 Na⁺ (g) + 2e⁻
B
2 H⁺ (aq) + 2e⁻ → H₂ (g)
C
Na⁺ (aq) + e⁻ → Na (s)
D
H₂ (g) → 2 H⁺ (aq) + 2e⁻
Correct Answer
Option A
Detailed Explanation
The reaction 2 Na (s)→ 2 Na⁺ (g) + 2e⁻ represents the oxidation half-reaction as sodium is losing electrons, which is consistent with the NCERT context.
