Question

Explain the role of NaCN in the extraction of silver is it
necessary to write reaction or fine to write answer asNaCN forms a
complex with Ag which again on reaction with Zn gives pure Ag So,
What should I expect with the examiner

Kumar Sarang · Accepted Answer

Extraction of Silver
Role of NaCN or KCN = In the extraction of gold
and silver, the metal is leached with NaCN or KCN, which is an
oxidation reaction

During the process, Ag is oxidised to Ag+

Here M =Ag or Au
Subsequent reaction with Zn leads to formation of free metal

You should write a reaction along with the explanation Reaction is
an important part of reasoning in this question
