Question

How to determine the Van't Hoff factor of a substance from its formula?

Answer 1

Van't Hoff factor

1. The Van't Hoff factor, "i", is the number of particles formed in a solution from one formula unit of solute.
2. The Van't Hoff factor is a relation between the ideal value of a solution's colligative properties and the observed colligative properties.
3. The formula for determining the Van't Hoff factor is $\mathrm{i}=\frac{\mathrm{measured}\mathrm{value}\mathrm{of}\mathrm{colligative}\mathrm{property}}{\mathrm{observed}\mathrm{value}\mathrm{of}\mathrm{colligative}\mathrm{property}}$
4. “i” does not depend on the concentration of solution.

Therefore, we can determine the Van't Hoff factor by measuring the solution and observed colligative properties.
