Solution

The correct option is A an increase in boiling point of the solution
When a solute dissolves in water, the vapour pressure of solvent decreases and because of this boiling point increases and freezing point decreases.

Q. Assertion: A

1 m N a C l (a q)

solution will freeze at a temperature below

273 K

.
Reason: As a solute is added to a solvent, the boiling point increases while the freezing point decreases.

When a substance is dissolved in a solvent the vapour pressure of the solvent is decreased. This results in:

Q. Read the passage given below and answer the following questions:
A soluble solid in solution has the effect of raising its boiling point and depressing its freezing point. The addition of non-volatile substances to a solvent decreases the vapor pressure and the added solute particles affects the formation of pure solvent crystals. According to many researches the decrease in freezing point directly correlated to the concentration of solutes dissolved in the solvent. This phenomenon is expressed as freezing point depression and it is useful for several applications such as freeze concentration of liquid food and to find the molar mass of an unknown solute in the solution. Freeze concentration is a high quality liquid food concentration method where water is removed by forming ice crystals. This is done by cooling the liquid food below the freezing point of the solution.
When a non-volatile solid is added to pure water it will

Q. Assertion :Addition of a non-volatile solute to a volatile solvent increases the boiling point. Reason: Addition of non-volatile solute results in lowering of vapour pressure.

Q. If 0.15 g of a solute, dissolved in 15 g of solvent, increases the boiling point by

{0.216}^{o} C

over that of the pure solvent, the molecular mass of the substance is (Molal elevation constant for the solvent is 2.16^OC$):
