Question

In redox reaction 1 g-eq of reducing agent requires P g-eq of oxidising agent. The value of P is

• A. 1
• B. 2
• C. 3
• D. Depends on reaction

Hint:

Redox reactions always obey the law of equivalence.

Answer 1

The Correct Option is A

Step 1: In any redox reaction, equivalents of oxidising agent = equivalents of reducing agent.
Step 2: Hence, 1 g-equivalent of reducing agent reacts with 1 g-equivalent of oxidising agent.
