In a solution, the liquid in which the solute dissolves is called the solvent. Solvents include water, propanone and ethanol. When a substance dissolves, solvent particles surround the solute particles. A saturated solution is a solution in which no more solute can dissolve. The solubility of a substance is the mass that dissolves in 100g of water. Every substance has its own solubility. The solubility of a substance varies with temperature. Substances that cannot dissolve in a certain solvent are insoluble in that solvent. Filtration separates a liquid from an insoluble solid. It also separates a solution from a solid that is mixed with is, but not dissolved. You can separate a solute from its solution by evaporation. You can separate a solvent from its solution by distillation. You can separate substances in a mixture by chromatography if all the substances are soluble in the same solvent. Chemistry Separation Techniques Quick Quiz – – What is the name of the process that occurs when salt is added to water and then stirred until the solid is no longer visible? Filtration Evaporation Dissolving In a solution of copper sulfate, what is the solvent? The water The copper sulfate The mixture What name is given to a substance that contains two types of atom that are not chemically joined together? Element Compound Mixture In a salt solution, what is the solute? The water The salty water The salt is the best way to get salt from salty water? Evaporation Filtration Distillation
