chemistry, a solution is a
homogeneous mixture composed of two or more substances. In such a mixture, a solute is a substance
dissolved in another substance, known as a
solvent. The mixing process of a solution happens at a scale where the effects of
chemical polarity are involved, resulting in interactions that are specific to
solvation. The solution assumes the phase of the solvent when the solvent is the larger fraction of the mixture, as is commonly the case. The
concentration of a solute in a solution is the
mass of that solute expressed as a percentage of the mass of the whole solution.
