Aqueous solution of KI dissolves I(2) to...

Aqueous solution of KI dissolves `I_(2)` to form `KI_(3)`. Which of the following statements is (are) true ?

A

The solution contains `K^(3+)` and `I^(-)` ions.

B

The solution contains `K^(+)` and `I_(3)^(-)` ions.

C

The solution is violet in colour.

D

In `KI_(3), I_(2)` behaves as Lewis acid and `I^(-)` as Lewis base.

Text Solution

Verified by Experts

The correct Answer is:
B, C, D
`KI(aq)+I_(2)(s)rarrKI_(3)(aq)+K^(+)(aq) +I_(3)^(-)(aq)` In polyhalide ion `I_(3)^(-)`, `I^(-)` behaves as a Lewis base and `I_(2)` as Lewis acid. `I_(3)^(-)` (aq) are violet coloured.
