Identify the following statement as true or false and choose the correct explanation. "For solutions with the same reverse osmotic pressure at the same temperature, the molarity of a sodium chloride solution will always be less than the molarity of a calcium chloride solution."
A)True, because the molar mass of sodium chloride is smaller.
B)True, because the van 't Hoff factor is smaller for sodium chloride.
C)False, because the van 't Hoff factor is smaller for sodium chloride.
D)False, because the van 't Hoff factor is larger for sodium chloride.
E)True, because the van 't Hoff factor is larger for sodium chloride.

Question

Quizplus · Accepted Answer

The van 't Hoff factor for sodium chloride is 2, while the van 't Hoff factor for calcium chloride is 3. Therefore, for solutions with the same reverse osmotic pressure at the same temperature, the molarity of a sodium chloride solution will always be less than the molarity of a calcium chloride solution.
