Match the following aqueous solutions with the appropriate letter from the column on the right.

We need to take into account the equation for boiling point elevation:

ΔT_{b} = K_{b} · b_{solute} · i

Where: bsolute = molality od the solution

K_{b}, the ebullioscopic constant, which is dependent on the properties of the solvent.

i. The Vant Hoff factor i accounts for the number of individual particles (typically ions) formed by a compound in solution

i= 3 For CaBr2

i=4 for FeCl3

i=4 for AlCl3

i=1 Glucose

then we need to find which solution have the highest ΔTb

1) ΔTb = Kb(0.17)x(3)= 0.51Kb

2)ΔTb = Kb(0.14)x(4)= 0.56Kb

3)ΔTb = Kb(0.12)x(4)= 0.48Kb

ΔTb = Kb(0.49)x(1)= 0.49Kb

Sorry I made a mistake in the second and third---but the letters are good

the order is

1-->B-Second

2-->A highest

3-->D lowest

4-->C third
