A gas ‘X' is passed through water to form a saturated solution. The aqueous solution on treatment with silver nitrate gives a white precipitate. The saturated aqueous solution also dissolves magnesium ribbon with evolution of a colourless gas 'Y’: Identify ‘X' and 'Y’.

Answer»

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

Solution :`Cl_(2)+H_(2)toHOCl+HCl`
`2HCL+"Mg"toMgCl_(2)+H_(2)UARR`
`Hence,(C( is the correct answer
