No method of prepn is given in Refs 2 or 3. Accd to Ref 4, p581, it cannot be prepd by dehydration of its hexahydrate, Co(Cl04)2.6H20, or of dihydrate, Co(C104)2.2H20. Cobaltic perchlorate, Co(ClOA)3, exists only in solns (Ref 4, P583)...

To test the applicability of the theoretical chemical relationships involving the two metals, a series of solutions containing manganese and cobalt perchlorate (total metal ion concentration near 10" M) was prepared, with Mn Co molar ratios from about 3 1 to about 50 1. These were precipitated and oxidized at pH 8.5 and later held at lower pH s, just as in the experiments described earlier. Some experiments also were made in which the cobalt was added after the manganese oxide had been precipitated. Experimental data from these solutions are given in Tables VIII-XI.
