Iodine is more soluble in aqueous solution of `KI` because it forms soluble
A) `KI_2`
B) `KI_3`
C) `KI_4`
D) `K_2I_2`

Why is I_2 more soluble in KI than in water?

A solution of KI_(3) in water contains :

Iodine is liberated from KI solution when treated with :

State True or False : I2 more soluble in KI than in water

Statement-I: When mercuric iodide(s) is added to the aqueous solution of KI , the freezing point is raised. Because Statement-II: HgI_(2) reacts with KI forming complex ion [Hg]_(4)^(2-)

Assertion (A): Due to common ion effect, the solubility of HgI_(2) is expected to be less in an aqueous solution of KI than in water. But HgI_(2) dissolves in an aqueous solution of KI to form a clear solution. Reason (R) : I^(Theta) ions is highly polarisable.

Give reason: Chlorine liberates iodine from KI solution

When HgI_(2) is added in KI solution. The freezing point of solution:-

KI and CuSO_4 solutions when mixed give

The number of moles of KI required to produce 0.4 mole K_(2)HgI_(4) is
