Question

In what way Kf and Kb are similar and in what way they
different?​

Answer 1

Answer:

Difference between Kf and Kb:

Kf is the depression in freezing point produced by 1 molal solution of a nonvolatile solute while Kb is the elevation in boiling point produced by 1 molal solution of a nonvolatile solute.

Answer 2

Answer:

The Kf and Kb have the same SI unit and the differences are Kb is elevation boiling point constant while Kf is depression freezing point constant.

Explanation:

Kb:- Molal elevation boiling point constant, basically it shows characteristics of solvents and it independent of the solute.

Kf:- Molal depression freezing point constant, it is also the characteristic of solvents and independent of solute.

Similarities between Kb and Kf are as follow:-

• Both Kf and Kb have the same SI unit of K Kg/mol.

• Their values depend only on the nature of the solvent and not on the type of solute that dissolved into it.

The difference between Kb and Kf are as follow:-

• Kb is the depression in freezing point produced by 1 molal solution of a nonvolatile solute.

• Kf is the elevation in boiling point produced by 1 molal solution of a nonvolatile solute.
