Periodic precipitation of cobalt(II) oxinate

The conditions for obtaining periodic precipitation of cobalt(II) oxinate in agar-agar gel are investigated. The dependence of the nature of periodic precipitation on the concentrations of inner and outer electrolytes is studied in detail. The spacing law of Jablczynski and the time law of Morse and Pierce are verified in this system. The dependence of velocity constant (K) and the spacing coefficient (p) on the concentrations of inner and outer electrolytes has been studied. The velocity constant shows a nonlinear variation with the concentrations of the inner and outer electrolytes. The spacing coefficient (p) is inversely proportional to the concentrations of the inner and outer electrolytes. According to Shouji Shinohara's revised flocculation theory, the flocculation values are computed. The dependence of the flocculation value on the concentrations of the outer and inner electrolytes is studied.
