Problem: Calculate the freezing point of a aqueous solution of K2SO4,Calculate the freezing point of a 0.100 m aqueous solution of K2SO4, taking interionic attractions into consideration by using the vant Hoff factor (i for 0.100 m K2SO4 = 2.32).

FREE Expert Solution

We’re being asked to determine the freezing point of an aqueous K2SO4solution. Aqueous means that K2SO4 was dissolved in water.


When calculating the freezing point of a solution, we’re going to use the Freezing Point Depression equation


Freezing Point Depression:

ΔTf =i·Kf·m 

where 

ΔTf = change in freezing point = Tf pure solvent  - Tf solvent

Kf = freezing point depression constant

i = van't Hoff factor of the solute = no. of ions

m = molality
