Methorics of the Precipitation from Electrolytic Solutions The Precipitation Bodies, PB, and Their Meaning for Determination of Characteristics of the Dispersed Phase, the Dispersing Medium, and the Methorical Layer

Using the method of continuous variation of concentration of the main precipitating components, as well as of the composition of the solution medium from which the precipitate emerges (genetic approach), the essential data for a precipitaUng system and the internal environment of the precipitating sub-systems may be obtained. The results are best presented in the form of the typical precipitation bodies · (PB), which are given as a plot of the logarithm of the concentration of the cationic component against the Jogarithm of the concentration of the anionic components; such plots show boundaries b etween precipitating and non-precipitating regions, as well as the discontinuities in the rate of precipitation -in general
