WebMay 27, 2014 · 1 Answer Ernest Z. May 27, 2014 Ionic solutes raise the boiling point more than nonionic solutes at the same concentration do. Boiling point elevation is a colligative property. It depends only on the number of particles in the solution. Solute particles are distributed throughout the solution. WebJul 6, 2024 · How does concentration affect freezing point? The more concentrated a solution, the more the freezing point of water will be depressed. The solute particles basically interfere with the ability of the water molecules to freeze because they get in the way and make it more difficult for the water to hydrogen bond.
