A) \[{{I}^{-}}\]
B) \[K{{I}^{-}}\]
C) \[KI_{2}^{-}\]
D) \[K{{I}_{3}}\]
Correct Answer: D
Solution :
odine readily dissolves in potassium iodide solution giving \[K{{I}_{3}}.\] \[KI+{{I}_{2}}\to K{{I}_{3}}(aq)\] \[K{{I}_{3}}(aq){{K}^{+}}(aq)+I_{3}^{-}(aq)\] Note: \[{{\text{I}}_{\text{2}}}\]is more soluble in an aqueous solution of KI than in pure water, it is due to the formation of polyhalide (\[\text{I}_{3}^{-}\]ion)You need to login to perform this action.
