Question

Identify the weakest oxidising agent among the following.

विकल्प

• Li⁺

• Na⁺

• Cd²⁺

• I₂

Answer 1

Li⁺ 

Explanation:

Due to the smaller size of lithium, it has the highest Hydration Enthalpy which compensate its I.E. and shows negative E° value. Therefore it acts as powerful reducing agent and hence weakest oxidising agent.
