Preferred Label : standard solution;
IUPAC definition : A solution of accurately known concentration, prepared using standard substances in
one of several ways. A primary standard is a substance of known high purity which
may be dissolved in a known volume of solvent to give a primary standard solution.
If stoichiometry is used to establish the strength of a titrant, it is called a secondary
standard solution. The term secondary standard can also be applied to a substance
whose active agent contents have been found by comparison against a primary standard.
Concentrations of standard solutions may be expressed in kmol m-3, mol dm-3, or in
terms more closely related to those used in specific titrations (as titres).;
