Standard Solution Definition - Chemistry Glossary

A standard solution is any chemical solution which has a precisely known concentration. Similarly, a solution of known concentration has been standardized. To prepare a standard solution, a known mass of solute is dissolved and the solution is diluted to a precise volume. Standard solution concentration is usually expressed in terms of molarity (M) or moles per liter (mol/L). Not all substances are suitable solutes for standard solutions. The reagent must be stable, pure, and preferably of high molecular weight. Source Freiser, Henry; Nancollas, George H. (1987). Compendium of Analytical Nomenclature: Definitive Rules 1987.
