Question

Cryoscopic constant of a liquid is-

• A. Decrease in freezing point when $1gram$ of solute is dissolved per kg of the solvent
• B. Decrease in the freezing point when $1mole$ of solute is dissolved per kg of the solvent
• C. Is the elevation for $1molar$ solution?
• D. Is a factor used for calculation of elevation in boiling point?

Answer 1

Answer: (B)

The cryoscopic constant is molal freezing point depression constant. It is decreasing in the freezing point of the solution when $1mole$ of Solute is dissolved in 1 kg of the solvent.
