NEET Chemistry Colligative Properties MCQ Question
Type: MCQ-conceptual-Medium-Class 12
We have three aqueous solutions of NaCl labelled as 'A', 'B' and 'C' with concentrations 0.1 M, 0.01 M and 0.001 M, respectively. The value of van't Hoff factor for these solutions will be in the order
A
iₐ < i_b < i_c
B
iₐ > i_b > i_c
C
iₐ = i_b = i_c
D
iₐ < i_c > i_b
Correct Answer
Option C
Detailed Explanation
The van't Hoff factor for NaCl is the same for all concentrations as it dissociates completely in solution.
