Expert Solution
Step 1

When a nonvolatile solute is added to a pure solvent it's freezing point decreases

The difference in freezing point of solution to that of pure solvent is called as depression in freezing point (∆Tf) 

The depression in freezing point depends on number of solute particles present in the solution and the molality of the solution by the relation 

∆Tf = i×Kf×m

i = van't Hoff factor = number of ions formed after complete dissociation of one mole electrolyte

Kf = freezing point constant = 1.86 °C/m for water

m = molality
