Solutions Question 1
Question 1 - 2024 (01 Feb Shift 1)
We have three aqueous solutions of $NaCl$ labelled as ’ $A$ ‘, ’ $^{\prime} B^{\prime}$ and ’ $C$ ’ with concentration $0.1 M, 0.01 M ~\& ~0.001 M$, respectively. The value of van $t^{\prime}$ Haft factor (i) for these solutions will be in the order.
(1) $i _A<i _B<i _C$
(2) $i _A<i _C<i _B$
(3) $i _A=i _B=i _C$
(4) $i _A>i _B>i _C$

Answer (1)
Solution
| Salt | Values of i (for different conc. of a Salt) | ||
|---|---|---|---|
| $0.1 M$ | $0.01 M$ | $0.001 M$ | |
| $NaCl$ | 1.87 | 1.94 | 1.94 |
1 approach 2 as the solution become very dilute.
