Question

The product formed when horn silver ore (chlorargyrite) is leached with aqueous $NaCN$ solution is:

• A. silver metal
• B. silver chloride
• C. silver cyanide
• D. sodium argentocyanide

Answer 1

The correct option is D sodium argentocyanide

When horn silver ore ($AgCl$) is leached with aqueous NaCN solution, sodium argentocyanide $\left(Na\right[Ag\left(CN{)}_2\right])$ is formed as a product.

The reaction is as follows:

$AgCl+2NaCN\to Na\left[Ag\right(CN{)}_2]+NaCl$

Option D is correct.
