Question:
Solubility of iodine in water may be increased by adding:
Solubility of iodine in water may be increased by adding:
Updated On: Jul 28, 2022
- chloroform
- potassium iodide
- carbon disulphide
- sodium thiosulphate
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The solubility of $I _{2}$ in water increases by the addition of KI due to formation of polyhalide ion, i.e., $I _{3}^{-}$.
$KI + I _{2} \longrightarrow KI _{3}$

Group 13 Elements
Group 13 is commonly known as the Boron Family. The boron family comprises:
- Boron (B)
- Aluminum (Al)
- Gallium (Ga)
- Indium (In)
- Thallium (Tl)
Element 113 (Nihonium) gets the name of ununtrium Uut. Each one of the elements has three electrons in the external shell of their nuclear structure is one of the important and mutual properties of the group.
The general electronic configuration for the group 13 elements is ns2 np1.
