Q. A solution of 1 molal concentration of a solute will have maximum boiling point elevation when the solvent is:

Assetion (A) When methyl alcohol is added to water, boiling point of water increases.
Reason (R) When a volatile solute is added to a volatile solvent elevation in boiling point is observed.

Q. Among the following which statements about boiling-point elevation is not true?
I. Addition of a nonvolatile solute raises the vapor pressure of a solution. Therefore, a higher temperature will be needed to produce boiling.
II. The molal concentration of solute particles dissolved in the solvent is an important factor in determining the molal boiling-point elevation constant.
III. The identity of solute particles dissolved in the solvent is an important factor in determining the molal boiling-point elevation constant.

Q. Assertion :Molal elevation constant depends on the nature of the solvent.
Reason: Molal elevation constant is the elevation in boiling point when

1 m o l e

of the solute is dissolved in

1 k g

of solvent.

If for a sucrose solution, elevation in boiling point is 0.1°C then what will be the boiling point of NaCl solution for same molal concentration
