Question

what is ebuloscopic and cryoscopic constant

Open in App

Solution

The elevation of boiling point of solution, when a non volatile solute impuriy is added is given by the formula
Î” T = K_b m . Here Î” T is rise in boiling point , m is molality of solution and K_bisebuloscopic constant. So K_b can be defined as change in boiling point of solvent in 1 molal solution.

The depression in freezing point of solution, when a non-volatile impurity is added is given by the formula
Î” T = K_f m Where Î” T is depression in freezing point, m is molality of solution and K_fis cryoscopic constant. so K_f is defined as change in freezing point of solvent in 1 molal solution.
