Question

In the given reaction:
2KAg(CN)2 +Zn2Ag+ K Zn(CN),
Write the oxidising and reducing agent.​

Answer 1

Answer:

ANSWER

In the given displacementliaction, silver is recovered from the cyanide complex by using highly electropositive metal, Zn.

2K(Ag(CN)2]+Zn→K2[Zn(CN)4]+2Ag↓

Here, oxidation state of silver changes from +1 to 0 and that of zinc changes from 0 to +2. Thus, Zn acts as a reducing agent and silver has been reduced
