Aq. Solution of which salt oxidise copper sheet :-

Options:(select one or more)

Answer:

A, C, D

Solution:

(A) Hg²⁺ → strong oxidizing agent, can oxidize Cu → Cu²⁺ (B) Mg²⁺ → very stable ion, cannot oxidize Cu (C) Hg₂²⁺ (mercurous ion) → unstable, gets reduced to Hg⁰, so can oxidize Cu (D) Ag⁺ → strong oxidizing agent, oxidizes Cu → Cu²⁺ Reactions:

$C u + 2 A g^{+} \to C u^{2 +} + 2 A g$

So, ions that oxidize a copper sheet are: A, C, D
