When a beaker with pure water is placed in a container containing a series beakers with aqueous solutions, the initial rates of water transfer to the solutions is the same for all solutions. Nevertheless, the escape rates of the water from each solution depends on the substance and initial concentration. It is possible to rank the average water transfer rate to the aqueous solutions of the same concentration containing calcium phosphate, glucose, magnesium chloride, and sodium chloride, respectively. These substances have different Van't Hoff factors.

Question

When a beaker with pure water is placed in a container containing a series beakers with aqueous solutions, the initial rates of water transfer to the solutions is the same for all solutions. Nevertheless, the escape rates of the water from each solution depends on the substance and initial concentration. It is possible to rank the average water transfer rate to the aqueous solutions of the same concentration containing calcium phosphate, glucose, magnesium chloride, and sodium chloride, respectively. These substances have different Van't Hoff factors.

Rank the rates, substance at the top of the sequence has the highest solvent molecule escape rate.
calcium phosphate, Ca3(PO4)2
magnesium chloride, MgCI2
glucose, C6H12O6
sodium chloride, NaCl

Answer 1

The ranking of the average water transfer rate to the aqueous solutions of the same concentration containing calcium phosphate, glucose, magnesium chloride, and sodium chloride, respectively, from highest to lowest is as follows:

1. Glucose, C6H12O6
2. Sodium chloride, NaCl
3. Magnesium chloride, MgCl2
4. Calcium phosphate, Ca3(PO4)2

This ranking is based on the different Van't Hoff factors of the substances, with glucose having the highest solvent molecule escape rate and calcium phosphate having the lowest.
