Question:medium

For an electrolyte undergoing association in a solvent, the van’t Hoff factor:

Show Hint

The van’t Hoff factor for association is less than one because the ions combine to form aggregates, reducing the number of particles in solution.

  • is always greater than one
  • has negative value
  • has zero value
  • is always less than one
Show Solution

The Correct Option is D

Solution and Explanation

When electrolytes associate, the particle count in solution diminishes due to the formation of ion pairs or clusters. Consequently, the van't Hoff factor falls below one, indicating fewer particles than would be predicted by dissociation alone.
