| Abstract: | Interaction energies between two similar plane parallel double layers for (NH4)2Fe(SO4)2 or (NH4)2Cu(SO4)2 type complex salt electrolytes at positive surface potential were expanded in a power series and accurate numeral results were given for 0.1 ≤ y e < y 0 ≤ 20. The general expressions were given for the interaction energies of A ν +B ν′ +Cν? type complex salt electrolytes at y > 0. The interaction energies for simple salts NaCl, CaCl2, Na2SO4, FeCl3, Na3PO4, Mg3(PO4)2, Al2(SO4)3, and complex salts (NH4)2Fe(SO4)2 or (NH4)2Cu(SO4)2 at y 0 = 1 were compared. There was hardly difference between these simple salts and this complex salt for the interaction energies. The interaction energy for complex salt (NH4)2Fe(SO4)2 was close to that for simple salt Na3PO4. Supplemental files are available for this article.
