Explains Raoult's Law and how it applies to solutions containing non-volatile solutes like salt. Shows how the lowering of vapour pressure affects the boiling point and freezing point of the solvent. ... This page deals with Raoult's Law and how it applies to solutions in which the solute is non-volatile - for example,

Having discussed concentration units we need to extend the idea of solutions to investigate how some physical properties of the solvent are effected upon addition of a nonvolatile solute. A nonvolatile solute is a solute which has little tendency to escape from the solution.

When a nonvolatile solute is added to a liquid to form a solution, the vapor pressure above that solution decreases. To understand why that might occur, let's analyze the vaporization process of the pure solvent then do the same for a solution.

A drop of solution containing nonvolatile solute is allowed to evaporate from a sphere-on-flat geometry. ... A drop of solution containing nonvolatile solute is allowed to evaporate from a sphere-on-flat geometry. Left behind is a striking pattern of gradient concentric rings with unprecedented regularity.

a 0.573g sample of a nonvolatile solute is added to 15.6g of napthalene and the mixture warmed until melted. The freezing point of the solution was determined and found equal to 78.1C. The freezing point of naphthalene is 80.2C. ... How do you find the molecular weight? Also how do I find the ... By OTA - Overall OTA Rating...
