• The osmotic pressure of a solution is proportional to the molar concentration of the solute particles in solution. (libretexts.org)
  • As we discussed at the beginning, the pressure that just stops the flow of solvent particles is the osmotic pressure. (toppr.com)
  • The key is that the solute is distinct from the solvent and disrupts the pattern of intermolecular forces normally present in the pure solvent, and the more solute particles the greater the disruption. (chadsprep.com)
  • Since the change in a colligative property is proportional to the number of solute particles present in solution, then a solute that dissociates into multiple ions will result in a larger change and the van't Hoff factor allows us to factor that in. (chadsprep.com)
  • Upon freezing these solute particles will put irregularities into the crystal structure which make it more difficult to form when compared to the pure solvent. (chadsprep.com)
  • The result is that the molecules must be moving even more slowly to 'freeze' into a solid which now occurs at a lower temperature than for the pure solvent, and the greater the concentration of solute particles, the lower the freezing point. (chadsprep.com)
