Question

In the extraction of silver from argentite ore, it is treated with dilute solution of NaCN in water in the presence of Y;
$A{g}_{2}X+4NaCN+2Y_2\to 2Na\left[Ag\right(CN{)}_2]+N{a}_{2}X{Y}_4$
$X$ and $Y$ in this reaction are represented by:

• A. $Cl$ and $S$
• B. $S$ and $O$
• C. $O$ and $O_2$
• D. $O$ and $Cl$

Answer 1

The correct option is B $S$ and $O$

$A{g}_{2}S+4NaCN+2O_2\to 2Na\left[Ag\right(CN{)}_2]+N{a}_{2}S{O}_4$
This process of extraction of $Ag$ is called cyanide process
