A solution is a homogeneous mixture of two or more substances, where one substance (the solute) is dissolved in another substance (the solvent). The solute is dispersed evenly throughout the solvent at a molecular level, resulting in a uniform composition throughout the solution. This means that the composition is the same no matter where you take a sample of the solution. Solutions can be aqueous (water-based), non-aqueous (not water-based), and can exist in various states of matter (solid, liquid, or gas).
