NEET Chemistry Van't Hoff Factor Assertion Reason Question
Assertion (A): The Van't Hoff factor for KCl in aqueous solution is approximately 2. | Reason (R): In dissociation, the van't Hoff factor is greater than unity.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Correct Answer
Detailed Explanation
The NCERT context states that the Van't Hoff factor for aqueous KCl is close to 2 due to dissociation into ions, which increases the number of particles, making i greater than unity.
