Identify the correct statement from following.
Options
- AThe vapour pressure of a solvent increases by dissolving nonvolatile solute into it.
- BThe boiling point of solvent decreases by dissolving a nonvolatile solute into it.
- CThe osmotic pressure of electrolytic solution is greater than nonelectrolytic solution of the same concentrati
- DThe freezing point of solvent is a colligative properly.
Correct answer
C. The osmotic pressure of electrolytic solution is greater than nonelectrolytic solution of the same concentrati
Step-by-step 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 i > 1 . Non-electrolytes do not disso
