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

Solubility of $BaF_2$ in a solution of $Ba(NO_3)_2$ will be represented by the concentration term?

The solubility of $BaSO_4$ in pure water is $10^{-5} \ M$ at $298 \ K$. The solubility of $BaSO_4$ in $0.1 \ M \ K_2SO_4$ (aq.) solution is: (Molar mass of $BaSO_4 = 233 \ g \ mol^{-1}$)

Given below are two statements:
Statement $I$: On passing $HCl_{(g)}$ through a saturated solution of $BaCl_2$,at room temperature white turbidity appears.
Statement $II$: When $HCl$ gas is passed through a saturated solution of $NaCl$,sodium chloride is precipitated due to common ion effect.
In the light of the above statements,choose the most appropriate answer from the options given below:

Addition of conc. $HCl$ to saturated $BaCl_2$ solution precipitates $BaCl_2$; because

In the absence of the formation of complex ions by the addition of a common ion,the solubility of a given salt is
