The lowest vapour pressure for 0.1 M solution exists for:
Correct answer: D. Al2(SO4)3
- A. Glucose
- B. NaCl
- C. BaCl2
- D. Al2(SO4)3
Explanation
The lowest vapour pressure would be observed in the case Al2SO4)3as it gives maximum no. of solute particles when dissolved due to dissociation.

About Solutions and Colloids
Solutions are described using molarity, molality, normality, mole fraction, percentage concentration and parts per million. Coverage also includes vapour-pressure lowering, boiling-point elevation, freezing-point depression and osmotic pressure, then distinguishes true solutions, colloids and suspensions by particle size, stability, light scattering and settling.
