When Cl_(2) water is added to a salt solution containing chloroform, chloroform layer turns violet. Salt contains

Answer»

`CL^(-)`<BR>`I^(-)`
`NO_(3)^(-)`
`S^(2-)`

Solution :As `Cl^(-)` is more electronegative than `Br^(-) and I^(-)`
`therefore` it replaces them from their salt as
`2I^(-)+Cl_(2) toI_(2)+2Cl^(-)implies`Violet vapour
`2Br^(-)+Cl_(2)toBr_(2)+2Cl^(-)implies`Brown vapour
