Question

The oxidation potentials of A and B are +2.37 V and +1.66 V respectively. In chemical reactions

• A. A will be replaced by B
• B. A will replace B
• C. A will not replace B
• D. A and B will not replace each other

Hint:

Key Exam Tip:
In displacement reactions, the more reactive element (or substance) displaces the less reactive element. Reactivity can be determined by:
• Oxidation Potential: A higher (more positive) oxidation potential means greater tendency to oxidize, hence higher reactivity.
• Reduction Potential: A lower (more negative) reduction potential means greater tendency to oxidize, hence higher reactivity. In this case, A has a higher oxidation potential than B, so A is more reactive.

Answer 1

The Correct Option is B
