Comparison of results of measuring acidity of aqueous salt solutions of HCl by electrometric and indicator methods

Conclusions A comparison of the results of measuring the acidity of aqueous salt solutions of HCl by the electrometric and indicator methods disclosed that the equation for the ionization of Hammett indicators should take into account the water that is firmly bonded to the proton and the ionized form of the base.Deceased.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 10, pp. 2381–2383, October, 1981.     

Cluster model of defective solid solutionsMe_{c_1 }^{(1)} Me_{c_2 }^{(2)} B_x^{(1)} B_y^{(2)}

In a cluster model of defective solid solutions the cluster components are determined and their concentration is found as a function of the defectiveness for solutions \(Me_{c_1 }^{(1)} Me_{c_2 }^{(2)} B_x^{(1)} B_y^{(2)}\) in the case of limited and unlimited solubility. An interpretation is given of the dependence of the lattice parameter, magnetic moment, and Curie point on the composition in a cluster component model, using the example of oxycarbides, oxynitrides, and solutions of certain metals in Mn₄N.
