When $H_2S$ gas is passed into a certain solution,it reacts to form a white precipitate. The solution referred to contains ions of

The solubility of $AgCl$ is least in which of the following solutions?

The following equilibrium exists in aqueous solution: $CH_3COOH \rightleftharpoons CH_3COO^{-} + H^{+}$. If dilute $HCl$ is added,without change in temperature,the:

Explain the common ion effect on the solubility of salts.

$A$ litre of solution is saturated with $AgCl$. To this solution if $1.0 \times 10^{-4} \ mol$ of solid $NaCl$ is added,what will be the $[Ag^{+}]$ compared to the original concentration,assuming no volume change?

The commercial salt is purified by passing
