The solubility of iodine in water increases in the presence of

A

Alcohol

B

Chloroform

C

Sodium hydroxide

D

Potassium trichloride

Text Solution

Verified by Experts

The correct Answer is:
D
Iodine has the least affinity for water and is only slightly soluble in it. However it is dissolved in 10% aqueous solution of Kl due to formation of complex ion i.e. `I_3^-` .
`I_2 + Kl hArr Kl_3 or I_2 + I^(-) hArr I_3^(-)` (Complex)
