Which of the following sulfides is completely precipitated upon dilution of its acidic solution?

Concentrated aqueous $NaOH$ can separate a mixture of

When calomel reacts with a solution of $NH_4OH$,which compound is formed?

On saturating an aqueous solution of $Cu(II)$,$Pb(II)$,and $Zn(II)$ ions with $H_2S$,which of the following will precipitate?

$A$ solution,when diluted with $H_2O$ and boiled,gives a white precipitate. On the addition of excess $NH_4Cl / NH_4OH$,the volume of the precipitate decreases,leaving behind a white gelatinous precipitate. Identify the precipitate which dissolves in $NH_4OH / NH_4Cl$.
