A gas X is passed through water to form ...

A gas X is passed through water to form a saturated solution. The aqueous solution on treatement with `AgNO_(3)` gives a white precipitate. The saturated aqueous solution also dissolves Mg ribbon with evolution of colourless gas `Y,X` and Y are respectively:

A

`CO_(2),CI_(2)`

B

`CI_(2),CO_(2)`

C

`CI_(2),H_(2)`

D

`H_(2),CI_(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
`underset((X))(Cl_(2))+H_(2)O rarr HOCl+HCl`
`AgNO_(3)+HCl rarr AgCl+HNO_(3)`
`Mg+2HCl rarr MgCl_(2)+underset((Y))(H_2)`.
