Question 6 • *25-26 KCS18 Chemistry IC

The osmotic pressure of a solution increases as

Answer
t
the boiling point of the solution decreases.
t
the amount of solvent in the solution increases.
t
the number of particles of solute in the solution increases.
t
the freezing point depression constant of the solution decreases.

Explanation

Osmotic pressure depends on the concentration of dissolved particles: at the same temperature and solution volume, more solute particles produce greater osmotic pressure. Therefore, it increases as the number of particles of solute increases. The boiling point and freezing point properties do not determine this relationship.
