Solubilities or relative concentrations of `I_(2)` in an aqueosu solution of KI are compared at a constant temperature of `25^(@)C`

Options

A. Solubility of `I_(2)` in water is more than in an aqueous solution of KI
B. Solubility of `I_(2)` in water is less than in an aqueous solution of KI
C. Solubility of `I_(2)` is same in both the cases
D. Solubility of `I_(2)` depends upon the external pressure.

Answer

B

Explanation

`I_(2)` is more soluble in n aqueous solution of KI, due to formation of polyhalide ion
`KI+I_(2) rarr K^(+)+[I_(3)]^(-)`
