Question

Which element has the highest oxidizing potential?

• A. Li
• B. Cu
• C. Al
• D. Mg

Hint:

The more negative the reduction potential, the stronger the oxidizing ability of the element.

Answer 1

The Correct Option is A

Lithium (\( Li \)) has the highest standard reduction potential, making it the strongest oxidizing agent: \[ E^\circ_{\text{Li}} = -3.04 \, \text{V}. \] 

Explanation: \( Li \) easily loses its single valence electron, making it highly reactive. 

Other elements like \( Cu \), \( Al \), and \( Mg \) have lower oxidizing potentials.
