Interpretation Introduction

Interpretation:

The extraction of silver from argentite ore, Ag2 S should be described.

Concept introduction:

The extraction of silver will be a reduction procedure. Here, a redox reaction would have to be written to explain the extraction of silver from Ag2 S.

The reaction will be set up on the basis of given information.

In this procedure of extraction, the argentite is first treated with sodium cyanide where it forms the sodium argento cyanide which is later reduced by zinc to precipitate the silver.
