🤓 Based on our data, we think this question is relevant for Professor Tisko's class at UN OMAHA.
We’re being asked to determine the freezing point and boiling point of an aqueous Na2SO4 solution. Aqueous means that Na2SO4 was dissolved in water.
When calculating the freezing point of a solution, we’re going to use the Freezing Point Depression equation. On the other hand, when calculating for the boiling point of a solution we’re going to use the Boiling Point Elevation equation.
Freezing Point Depression:
∆Tf = change in freezing point = Tf pure solvent –Tf solution
Kf = freezing point depression constant
i = van' t Hoff factor of the solute = no. of ions
m = molality
Boiling Point Elevation:
Assuming 100% dissociation, calculate the freezing point and boiling point of 2.96 m Na2SO4(aq).
