ChemistryMediummultiple choice

Which can convert $I^{-}$ to $I_{2}$ :-

Answer:

A, C, D

Solution:

To convert I⁻ to I₂, the species must act as an oxidizing agent.

NO₂⁻ → can oxidize I⁻ to I₂

MnO₄⁻ / OH⁻ → in basic medium it is a weaker oxidant and does not effectively oxidize I⁻ to I₂

Fe³⁺ / H⁺ → Fe³⁺ oxidizes I⁻ to I₂

CuSO₄ (Cu²⁺) → Cu²⁺ oxidizes I⁻ to I₂ forming CuI

Correct answer: (A), (C), (D)
