Question

A 1 m solution of MgCl2 will cause the decrease in the freezing point of water to be approximately ___ than that caused by a 1 m solution of sucrose



a. 3x kleiner/ 3x smaller

b. 2x kleiner / 2x smaller

c. dieselfde / the same

d. 2x groter / 2x greater

e. 3x groter / 3x greater

f. nie een van bogenoemde nie / none of the above

Answer 1

Sucrose does not ionize. MgCl2 ionizes into three particles. Since the depression of the freezing point is proportional to the number of particles, th MgCl2 will depress 3x greater.

Answer 2

3 times greater
