The correct relationship between the boiling points of very dilute solutions of `AlCl_(3) (t_(1))` and `CaCl_(2)(t_(2))`, having the same molar concentration, is

A

`t_(1)-t_(2)`

B

`t_(1)gtt_(2)`

C

`t_(2)gtt_(1)`

D

`t_(2)get_(1)`

Text Solution

Verified by Experts

The correct Answer is:
B
`AlCl_(3)` furnishes more ions than `CaCl_(2)` and thus shows higher boiling point.

The Van't Hoff factor of very dilute solution of Ca(NO_(3))_(2)

A system of greater disorder of molecules is more probable. The disorder of molecules is reflected by the entropy of the system. A liquid vapourizes to form a more disordered gas. When a solute is present, there is additional contribution to the entropy of the liquid due to increased randomness. As the entropy of solution is higher than that of pure liquid, there is weaker tendency to form the gas. Thus, a solute (non-volatile) lowers the vapour pressure of a liquid, and hence a higher boiling point of the solution. Similarly, the greater randomness of the solution opposes the tendercy to freeze. In consequence, a lower temperature must be reached for achieving the equilibrium between the solid (frozen solvent) and the solution. The elevation in boiling point (DeltaT_(b)) and depression in freezing point (DeltaT_(f)) of a solution are the colligative properties which depend only on the concentration of particles of the solute and not their identity. For dilute solutions, (DeltaT_(b)) and (DeltaT_(f)) are proportional to the molarity of the solute in the solution.

The osomotic pressure pi depends on the molar concentration of the solution (pi=CRT) . If two solutions are of equal solute concentration and, hence, have the same omotic pressure, they are said to be isotonic. If two solutions are of unequal osmotic pressures, the more concentrated solution is said to be hypertonic and the more diluted solution is described as hypotonic. Osmosis is the major mechanism for transporting water upward in the plants.
