Assuming water is the solvent in the two solutions, potassium nitrate and glycerin increased the boiling point of the water in the same amount. Recall the formula of boiling point elevation:

Potassium Nitrate (KNO3) is an electrolyte and will break up into its ions in the solution: KNO3  K­+ + NO3+. The van’t Hoff factor for KNO3 would be: i = 2
