When 2.36 g of a nonvolatile solute is dissolved in 100 g of solvent,the largest change in freezing point will be achieved when the solvent is A)benzene,K_f = 5.07. B)camphor,K_f = 37.8. C)chloroform,K_f = 4.70. D)All are expected to have the same freezing point.

Question

Quizplus · Accepted Answer

The largest change in freezing point will be achieved with the solvent that has the highest cryoscopic constant (K_f). Therefore, choosing camphor (K_f = 37.8) would result in the largest change in freezing point. The other solvents have lower cryoscopic constants, and thus would result in smaller changes in freezing point.
