Solubility and conductance of lanthanum ferricyanide in water

Abstract

The solubility of lanthanum ferricyanide in water, over the temperature range 0·5–35°, and in potassium chloride and magnesium sulphate solutions at 25° has been measured. The solubility in water was found to be much greater than had previously been reported, and, moreover, it was possible to prepare supersaturated solutions of a high apparent stability by indirect methods. The conductance curve at 25° could thus be extended up to 0·77N; it shows a minimum value at ca. 0·1N, followed by a maximum.
