### 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 |
