NEET Chemistry Van't Hoff Factor MCQ Question
Which of the following combinations accurately describes the van't Hoff factor, i, for solutes in solution?
i is greater than 1 for dissociation and less than 1 for association.
i is equal to 1 for all solutes regardless of association or dissociation.
i is always greater than the number of particles before dissociation.
i is less than 1 for all ionic compounds in solution.
Correct Answer
Detailed Explanation
According to the NCERT context, the value of i for dissociation is greater than unity, while for association, it is less than unity. This indicates the behavior of solutes when they dissociate into ions or associate into larger particles.
