A solution is a homogeneous mixture composed of two or more substances, consisting of a solute dissolved uniformly within a solvent. The formation of a solution requires that the constituent particles of the solute are completely dispersed within the solvent and remain suspended indefinitely, resulting in a substance with uniform composition throughout. The concentration of the resulting solution can be quantified using various scientific metrics, such as molarity, molality, or percent composition, which relate the quantitative amount of the dissolved substance to the amount of the solvent or the total mass of the solution. Solutions are fundamental to chemical analysis and industrial processes, enabling controlled chemical reactions and the creation of stable chemical mixtures.
