Question

Which is strong reducing agent Cr²⁺ or Fe²⁺.

Answer 1

Cr⁺² is Strong reducing agent.

Reducing agent :- The tendency to loose electrons or to undergoes oxidation easily.

→  It based on the number of maximum electrons that it can given out

→  We know for Cr +6 is maximum, So Cr⁺² can lose 4e⁻

→  But for Fe +3 is maximum, So Fe⁺² can lose only 1e⁻
