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 = 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
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).
