摘要: It has been attempted to determine the binding ratio of strontium and cobalt atoms in monolayer stearic acid spread on aqueous solutions, respectively, containing radioactive cations. The number bound one molecule increased with increasing pH substrate solution as well concentration ion it. Tentative explanation was made by assuming interaction between stearate ions. A theoretical formula based ioniza-tions acid, hydroxide, proved support validity this presumption. similar also for cobaltous chloride less than 6.5, where showed no expansion but rather a small condensation, while Co per up 0.5. At 7–9, remarkably expanded compressible fi...
