Important Properties of Compounds of Silver

Dilute nitric acid on reaction with silver liberates ${\mathrm{N}}_2$ gas.

Dilute nitric acid on reaction with silver liberates:

Silver metal reacts with hot concentrated nitric acid and produce silver nitrate $\left({\mathrm{AgNO}}_3\right)$ salt, nitrogen dioxide $\left({\mathrm{NO}}_2\right)$ gas and water as products.

What happens when silver reacts with Hot Conc. ${\mathrm{HNO}}_3$.

In the reaction $2\mathrm{Ag}+2{\mathrm{H}}_2{\mathrm{SO}}_4\to {\mathrm{Ag}}_2{\mathrm{SO}}_4+2{\mathrm{H}}_2\mathrm{O}+{\mathrm{SO}}_2$, sulphuric acid acts as an acid as well as an oxidant.

In the reaction $2\mathrm{Ag}+2{\mathrm{H}}_2{\mathrm{SO}}_4\to {\mathrm{Ag}}_2{\mathrm{SO}}_4+2{\mathrm{H}}_2\mathrm{O}+{\mathrm{SO}}_2$, sulphuric acid acts as :

The black coating in silver is due to the formation of silver sulphide.

Why is there a black coating in silver?

Silver articles become black on prolonged exposure to air. This is due to the formation of silver sulphide.

Silver articles become black on prolonged exposure to air. This is due to the formation of

Cotyledons are also called-

Aqueous solution of metallic nitrate $X$ reacts with $N{H}_{4}OH$ to form Y which dissolves in excess $N{H}_{4}OH$. The resulting complex is reduced by acetaldehyde to deposit the metal. $X$ and $Y$ respectively, are

Three separate samples of a solution of a single salt gave these test results, one formed a red/brick red precipitate with,potassium chromate solution,one formed a white precipitate with excess ammonia solution and one formed a black precipitate with $H_{2}S$ . The salt could be
