Solutions Question 1
Question 1 - 2024 (01 Feb Shift 1)
We have three aqueous solutions of $\mathrm{NaCl}$ labelled as ’ $A$ ‘, ’ $^{\prime} B^{\prime}$ and ’ $C$ ’ with concentration $0.1 \mathrm{M}$, $0.01 \mathrm{M} ~& ~0.001 \mathrm{M}$, respectively. The value of van $\mathrm{t}^{\prime}$ 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) | ||
|---|---|---|---|
| $0.1 \mathrm{M}$ | $0.01 \mathrm{M}$ | $0.001 \mathrm{M}$ | |
| $\mathrm{NaCl}$ | 1.87 | 1.94 | 1.94 |
1 approach 2 as the solution become very dilute.
