NEET Chemistry Van't Hoff Factor MCQ Question
A diagram shows a series of solutions of K2SO4 at varying molal concentrations being tested for colligative properties. Which of the following best describes the trend in the van't Hoff factor (i) as the concentration of K2SO4 decreases?
The van't Hoff factor approaches 3.00 as the concentration decreases.
The van't Hoff factor remains constant regardless of concentration.
The van't Hoff factor decreases as concentration decreases.
The van't Hoff factor approaches 1.00 as the concentration decreases.
Correct Answer
Detailed Explanation
As per the NCERT context, the van't Hoff factor for K2SO4 approaches 3.00 as the concentration decreases, indicating more complete dissociation at lower concentrations.
