WebAnswer (1 of 3): If the solute present in the solution gets dissociated or associated, then the observed value of colligative properties (you might want to look it up if you're unsure what it means) is different from the theoritically calculated value. This … The van 't Hoff factor i (named after Dutch chemist Jacobus Henricus van 't Hoff) is a measure of the effect of a solute on colligative properties such as osmotic pressure, relative lowering in vapor pressure, boiling-point elevation and freezing-point depression. The van 't Hoff factor is the ratio between the actual concentration of particles produced when the substance is dissolved and the concentration of a substance as calculated from its mass. For most non-electrolytes dissolved in …

The van

There are a few different ways of writing the formula to calculate the van’t Hoff factor. The most common equation is: i = moles of particles in solution / moles dissolved solute Because solutes don’t always fully dissociate in solution, there is another relation that is often used: i = 1 + α(n – 1) Here, α is the fraction of … Ver más For solutes that dissolve in water, the van’t Hoff factor is 1.
