The Formula Explained
The van't Hoff factor (i) is calculated using the formula: i = \frac{\text{number of particles in solution after dissociation}}{\text{number of formula units initially dissolved}}
Glossary of Variables
- Compound: The chemical substance being dissolved.
- Concentration (mol/L): The molarity of the solution.
- van't Hoff Factor: The calculated number showing the effect on colligative properties.
Practical Example
How It Works: A Step-By-Step Example
For a 0.1 mol/L solution of NaCl, the van't Hoff factor is expected to be close to 2, since NaCl dissociates into two ions: Na⁺ and Cl⁻.
Frequently Asked Questions (FAQ)
What is the van't Hoff factor?
It measures the effect of solute particles on the colligative properties of a solution.
Why is it important?
Understanding the van't Hoff factor helps predict changes in boiling point, freezing point, and osmotic pressure.
How do I determine the correct factor?
It depends on the degree of dissociation of the solute in the solution.
What is the formula used?
The formula is: i = \frac{\text{number of particles in solution after dissociation}}{\text{number of formula units initially dissolved}}
Can it change with concentration?
Yes, the van't Hoff factor can vary depending on the concentration and the extent of dissociation or association of the solute.
