This document discusses mixtures and solutions. It defines a mixture as a combination of two or more substances that are mixed but not chemically combined. There are two types of mixtures: homogeneous, which appear uniform throughout, and heterogeneous, where the elements can be seen separately. A solution is a homogeneous mixture with only one phase that cannot be separated by filtration. It is composed of a solute dissolved in a solvent. The document discusses saturated, unsaturated and supersaturated solutions, and how to calculate the concentration of solutions by mass or volume.
