Solutes, Solvents, and Separating Mixtures
Learning Objective
I can describe how a solute dissolves in a solvent and how mixtures can be separated.
Key Concepts
A mixture is a combination of two or more substances that do not chemically change when combined, while a solution is a type of mixture where one substance dissolves evenly into another.
In a solution, the substance that dissolves is called the solute, and the substance it dissolves into is called the solvent; during dissolving, the solute particles move between the solvent particles until evenly distributed.
Mixtures can be separated through methods like sifting, filtration, magnetism, or evaporation, while solutions can be separated by changing the phase of matter, such as boiling to evaporate the solvent.
