Question

When 11.7 g of sodium chloride are dissolved in 200 gm of water, the depression in freezing point is double than the depression caused by 342 gm of cane sugar in 1000 gm of water. From this information, what do you infer about the i of sodium chloride in the solution?

Answer:

2

Solution:

$(Δ T_{f})_{N a Cl} = 2 (Δ T_{f})_{S ug a r}$

$\displaylines i k_{f} \frac{0.2 \times 1000}{1 \times 200} = 2 k_{f} i = 2$
