Few drops of salt solution are shaken with chloroform followed by chlorine water. Chloroform layer becomes orange. Solution contains:

Options

A. `NO_(2)^(-)` ions
B. `NO_(3)^(-)` ions
C. `Br^(-)` ions
D. `I^(-)` ions

Answer

C

Explanation

The orange colour in chloroform layer is due to `Br_(2)` gas liberated from the solution containing `Br^(-)` ions
`2NaBr + Cl_(2) rarr 2 NaCl + underset(("orange colour"))(Br_(2))`
