Question

Q 8. Which of the following statement is
incorrect about colligative properties
​

Answer 1

Explanation:

All the colligative properties do not depend on the type of solute but rather on the quantity of solute. As long as quantity or concentration is same, their colligative properties are also same.

0.1M KCl solution will have same osmotic pressure as 0.1M Glucose solution as their molarities are same.

0.1M KCl solution will have the same boiling point as 0.1M urea solution as their molarities are same.

van’t Hoff factor for MgCl

 is 2 and for NaCl, it is 1. The change in relative lowering of vapor pressure depends on van’t Hoff factor. 0.1M MgCl

2

​

 solution will have less relative lowering of vapor pressure than 0.1M NaCl
