The boiling point of `0.1 M KCl` solution is ………..than `100^(@)C`.

Statement The boiling point of 0.1 M urea solution is less than that if 0.1M KCl solution. Elevation of boiling point is directly proportional to the number of species present in the solution.

Assertion (A): The boiling point of 0.1 M solution is less that that of 0.1 M'KCl solution. Reason (R): Elevation of boiling point is directly proportional to the number of species present in the solution.

Elevation in boiling point of 0.1 m CaCl_(2) , solution less / more than 0.1 m NaCl solution.

The boiling point of an aqueous solution is 100.18 .^(@)C . Find the freezing point of the solution . (Given : K_(b) = 0.52 K kg mol^(-1) ,K_(f) = 1.86 K kg mol^(-1))

A solute A dimerizes in water. The boiling point of a 2 molal solution of A is 100. 52^@C . The percentage association of A is ............ (Round off to the Nearest Integer). ["Use "K_b " for water "=0.52 "K kg mol"^(-1) " Boiling point of water "=100^@C]

Give reasons for the following : (a) Measurement of osmotic pressure method is preferred for the determination of molar masses of macromolecules such as proteins and polymers . (b) Aquatic animals are more comfortable in cold water than in warm water . (c) Elevation of boiling point of 1M KCl solution is nearly double than that of 1 M sugar solution.
