How does molality affect freezing point

WebThe 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. Was this answer helpful? 0 0 Similar questions WebFreezing point depression is the phenomena that describes why adding a solute to a solvent results in the lowering of the freezing point of the solvent. When a substance starts to freeze, the molecules slow down due to the decreases in temperature, and the intermolecular forces start to take over.
