Preferred Label : stoichiometric concentration;
Detailed label : stoichiometric concentration, c;
IUPAC definition : The stoichiometric concentration, cB, of a component B in a system is given by the
expression: \[c_{{B}} \frac{n_{{B}}}{V}\] where n B is the stoichiometric amount of
substance of component B in the system and V is the volume of the system. The component
added to the system may dissociate or react with other components to form a series
of derived components and only a fraction of the original component may actually exist
in a free form in the system. It is therefore essential to distinguish between the
stoichiometric concentration and the amount-of-substance concentration of the free
form of the component in the system. Sometimes stoichiometric quantities are indicated
by a subscript (o), e.g. n o,B, co,B. In clinical chemistry, the term stoichiometric
concentration is rarely employed. Instead, the name of the component is modified to
indicate inclusion of the various derived forms, e.g. mixtures of a defined chemical
component and its derivatives may be denoted by the plural form of the name of the
pure unchanged substance, or to indicate the sum of components specified in individual
quantities the specification 'total' may be employed.;
