In the presence of $HCl$,$H_2S$ results in the precipitation of Group-$2$ elements but not Group-$4$ elements during qualitative analysis. It is due to

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:

At equilibrium,if $HCl$ gas is passed through a saturated solution of $NaCl$,$NaCl$ gets precipitated because:

Which of the following will not have its ionization suppressed by the addition of $HCl$?

$25 \ mL$ of silver nitrate solution $(1 \ M)$ is added dropwise to $25 \ mL$ of potassium iodide $(1.05 \ M)$ solution. The ion$(s)$ present in very small quantity in the solution is/are $........$.

Reaction between $NaCl$ and $AgNO_3$ can be suppressed by
