JEE Main 2024 — Solutions Question with Solution

JEE Main 2024 (01 Feb Shift 1)

Question

We have three aqueous solutions of NaCl labelled as ‘A’, ‘B’ and ‘C’ with concentration 0.1 M, 0.01M and 0.001 M, respectively. The value of van t’ Haft factor i for these solutions will be in the order.

Choose an option

Show full solutionCorrect option: A
Correct answer
AiA<iB<iC

Step-by-step explanation

It is because the extent or degree of dissociation increases with increase in dilution of a solution. 0.001 M NaCl solution 'C' is most diluted as compared to the other two NaCl solutions. The vant Hoff factor (i) depends on extent of dilution.This confirms answer at (i) iA<iB<iC
