Conclusion
The study of the interaction of calcium chloride with sodium carbonate reveals the following facts:
-
1.
The Liesegang phenomenon may take place in the absence of a limiting initial colloidal medium, the interaction of the electrolytes constituing a source of colloidal matter.
-
2.
This colloidal dispersion may be stable both in air and in an aqueous medium. A wide range of periodic formations come into being under conditions rendering the colloidal state transitory in character. These structures comprise both compact (asbestos-like layers and arboreal growth) and dispersed (opacity bands and streamers) forms.
-
3.
The conditions of reaction leading to the dispersed colloidal system strongly support the possibility of these serving as the basis of the colloidal substrate in photosynthesis.
