title: Graphical analysis of the formation function-II: the pseudo cross-over point.
abstract: In a further attempt to enhance the possibility of interpreting the formation function, a number of special shapes of the formation function are discussed, which give rise to a pseudo cross-over point. It is shown that under certain conditions a pseudo cross-over point can be found in the following cases: (1) two series of homonuclear complexes, (2) a mixture of a series of homonuclear and polymeric complexes, (3) a series of mononuclear complexes and two polynuclear complexes with nearly the same composition, (4) a system which gives a real cross-over point, and one or more polynuclear complexes, (5) a system of two polynuclear complexes. The conditions are mainly discussed in terms of the composition of the complexes. Calculated curves illustrate the different possibilities.
