A) Addition of KCN
B) Oxidation of Ag
C) Oxidation of Zn
D) Reduction of Ag​

Answer 1

Answer:

A) Addition of KCN.

Explanation:

hope it helps...

Answer 2

Answer:

B) Oxidation of Ag

Explanation:

KCN ⇄ K⁺ CN⁻

Displacement from aqueaus solution

Ag₂s +4CN⁻ ---------> 2[Ag(CN)₂]⁻ + s⁻²

2[Ag (CN)⁻₂aq + Zn ----------> Zn [(CN)₄]⁻² + 2Ag

                                                                      ↓

                                                       Reduction OF Ag

Ag₂s dissolve in KCN soln dicyon oxygenate

(I)ion

These steps is not involved in the extraction of Ag

B) Oxidation of Ag
