Question

Quizplus · Accepted Answer

The ratio of actual value to calculated value is described by the van't Hoff factor, which determines the extent of dissociation of a solute into ions in a solution. This factor is only applicable to electrolytes, as nonelectrolytes do not dissociate into ions. Choices A, B, D, and E are all colligative properties, but do not relate to the ratio of actual to calculated value.
