Calculate the molality and van’t Hoff factor (i) for the following aqueous solutions:
(a) 0.500 mass % KCl, freezing point = - 0.234°C

Respuesta :

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 water, the van 't Hoff factor is essentially 1.

What is the value of Van t Hoff factor?

For most non-electrolytes dissolved in water, the Van 't Hoff factor is essentially $ 1 $ . For most ionic compounds dissolved in water, the Van 't Hoff factor is equal to the number of discrete ions in a formula unit of the substance.

  A. Sodium chloride.

  B. Magnesium chloride.

  C. Sodium phosphate.

  D. Urea.
