Problem: Which of these aqueous solutions has the highest boiling point?a) 1.25 M C6H12O6b) 1.25 M KNO3c) 1.25 M Ca(NO3)2d) None of the above (they all have the same boiling point)

FREE Expert Solution

ΔT­b is given by:


ΔTb=Tb, solution-Tb, pure solvent


The change in boiling point is also related to the molality of the solution:


ΔTb=imKb

where: 

i = van’t Hoff factor

m = molality of the solution (in m or mol/kg)

Kb = boiling point elevation constant (in ˚C/m) of the solvent
