Chemistry - Liquid Solution Question with Solution | TestHub
Identify the correct statement from following.
Options:
Answer:
Solution:
When a non-volatile solute is added to a solvent, the vapour pressure of the solvent decreases. This is known as the relative lowering of vapour pressure.
Due to the lowering of vapour pressure, the boiling point of the solution increases. This is known as the elevation in boiling point.
Osmotic pressure is a colligative property, meaning it depends on the number of solute particles in the solution. Electrolytes dissociate into ions in solution, resulting in a van't Hoff factor . Non-electrolytes do not dissociate, so . Since osmotic pressure , an electrolytic solution will have a greater osmotic pressure than a non-electrolytic solution of the same concentration.
The depression in freezing point is a colligative property, not the freezing point itself.
Answer: The osmotic pressure of electrolytic solution is greater than nonelectrolytic solution of the same concentration.
