Question

Which of the following statements is incorrect?

• A. Co³⁺ and Fe²⁺ have same number of unpaired electrons.
• B. Of all the known elements, Silver has the highest electrical conductivity at room temperature.
• C. To form a substitute alloy, the difference between the atomic radii of solvent and solute atoms should be less than 15%.
• D. If the standard electrode potential (E^) of a metal is large and negative, the metal is a powerful oxidising agent.

Hint:

To remember redox strength: - More Negative E^: Stronger Reducing Agent (Best at losing electrons). - More Positive E^: Stronger Oxidising Agent (Best at gaining electrons).

Answer 1

The Correct Option is D
