Type: MCQ-conceptual-Medium-Class 12
Which of the following reactions is possible at anode?
A
2Cr³⁺ + 7H₂O → Cr₂O₇²⁻ + 14H⁺
B
F₂ → 2F⁻
C
1/2O₂ + 2H⁺ → H₂O
D
None of these
Correct Answer
Option A
Detailed Explanation
At the anode, oxidation occurs. The reaction 2Cr³⁺ + 7H₂O → Cr₂O₇²⁻ + 14H⁺ involves the oxidation of Cr³⁺ to Cr₂O₇²⁻, making it possible at the anode.
