A gas 'X' is passed through water to form a solution. The aqeous solution on treatment with `AgNO_(3)` solution gives a white precipitate. The sturated aqueous solution also dissolves magnesium ribbon with the evolution of colourless gas 'Y'. Identify 'X' and 'Y'

A

`X = CO_(2), Y = Cl_(2)`

B

`X = Cl_(2), Y = CO_(2)`

C

`X = Cl_(2), Y = H_(2)`

D

`X = H_(2), Y = Cl_(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 underset(("White ppt"))(AgCl) + HNO_(3)`
`Mg + underset((X))(Cl_(2)) rarr MgCl_(2) + underset((Y))(H_(2))`
