Question

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

• A. is always greater than one
• B. has negative value
• C. has zero value
• D. is always less than one

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.

Answer 1

The Correct Option is D

For electrolytes undergoing association, the number of particles in solution decreases because ions form pairs or clusters. This results in a van’t Hoff factor less than one, as fewer particles are present than expected based on dissociation alone.
