write about the Depression in freezing point
Answers
Answer:
freezing point of a liquid is the temperature at which liquid and solid are in equilibrium and the two phases have the same vapour pressure.The general experimental observation is that the freezing point of a solvent is lowered by dissolving a nonvolatile solute into it. Thus, freezing point of solution containing a nonvolatile solute is lower than that of pure solvent.
Explanation:
Freezing point depression is a colligative property observed in solutions that results from the introduction of solute molecules to a solvent. The freezing points of solutions are all lower than that of the pure solvent and is directly proportional to the molality of the solute.
OR
Freezing 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.
