Abstract
RECENTLY, Rastogi, Batra and Dass1 have reported that potential differences are produced when crystals of an electrolyte just appear or when they are allowed to dissolve. The former has been called the precipitation potential and the latter the dissolution potential. One of the important conclusions of this study is that the dissolution potential of an electrolyte, in an aqueous solution of the same, is a function of the concentration and that its value increases as the dilution is increased. The dissolution potential was also seen to increase systematically in most cases as the temperature of the water is increased. This seems logical, for the dissolution potential must be related in some manner to the solubility of the electrolyte as the term implies.
