Preferred Label : laws of distribution;
Detailed label : laws of distribution in precipitation;
IUPAC definition : During the formation of a mixed crystal from a solution containing two components
'A' and 'B', the latter may be distributed according to the equation \[K_{{A},{B}}
\frac{b\ (a_{0}- a)}{a\ (b_{0}- b)}\] In this homogeneous distribution, a0 and b0
are the respective concentrations in the solution before crystallization and a and
b are the respective concentrations in the solution after crystallization. KA,B is
usually called the separation factor. The term homogeneous distribution coefficient
is not recommended. Alternatively the distribution of the micro-component may follow
the equation of Doerner and Hoskins \[\ln (\frac{a_{0}}{a}) \lambda \ \ln (\frac{b_{0}}{b})\]
(logarithmic distribution) where λ is usually called the logarithmic distribution
coefficient, the meaning of the other symbols remaining the same. Exactly homogeneous
or logarithmic distributions are extreme cases and very seldom encountered.;
