NEET Chemistry Van't Hoff Factor MCQ Question
What is the van't Hoff factor (i) for a completely dissociated solute like NaCl in solution?
Greater than 1
Less than 1
Equal to 1
Always zero
Correct Answer
Detailed Explanation
For a solute that completely dissociates, such as NaCl, the van't Hoff factor (i) is greater than 1, because it produces more particles in solution than it originally had. This is evident from the NCERT context which states that for dissociation, the value of i is greater than unity.
