Question

A gas X is passed through water to form saturated solution. The aqueous solution on treatment with $A g N O_{3}$ gives a white precipitate. The saturated aqueous solution also dissolves magnesium ribbon with evolution of a colorless gas $Y$ . Identify $X$ and $Y$ .

X = C O_{2}

Y = C l_{2}

Solution

The correct option is C $X = C l_{2}$ , $Y = H_{2}$
Gas is $C l_{2}$ as
$C l_{2} + A g^{+} \to A g C l$ white ppt.
and aq. solution of this gas gives hydrogen gas.
