Iodine readily dissolves in potassium iodide solution giving

A

`I^-`

B

`KI_2`

C

`KI_2^-`

D

`KI_3`

Text Solution

Verified by Experts

The correct Answer is:
D
`l_2` is more soluble in an aqueous solution of KI than in pure water. It is due to the formation of polyhalide (triiodide, `I_3^-` ion). `KI(aq) +I_2(s)to KI_3 (aq) KI_3 (aq) to K^(+) (aq) + I_3^(-)(aq) `
