Chapter 17, Problem 81E

Consider the following solutions:
0.010 m ${\text{Na}}_{\text{3}}{\text{PO}}_{\text{4}}$ in water
0.020 m ${\text{CaBr}}_{\text{2}}$ in water
0.020 m KCl in water
0.020 m HF in water (HF is a weak acid.)
a. Assuming complete dissociation of the soluble salts,which solution(s) would have the same boiling pointas 0.040 m ${\text{C}}_{\text{6}}{\text{H}}_{\text{12}}{\text{O}}_{\text{6}}$ in water? ( ${\text{C}}_{\text{6}}{\text{H}}_{\text{12}}{\text{O}}_{\text{6}}$ is anonelectrolyte.)
b. Which solution would have the highest vapor pressureat 28°C?
c. Which solution would have the largest freezingpointdepression?
