Essay

The results of potentiometric, thensiometric, thermodynamic investigations of fluor-containing compounds behavior in wet phosphoric acid produce are defended. The autothentic ionization constants of hexafluorosilicic and pentafluorosilicic acids data were obtained firstly. Fluoride compounds quantitative and qualitative composition in gas phase above technological solutions that contain phosphorus and fluorosilicic compounds was established. The mechanism of calcium and magnesium hexafluorosilicates into these metals difluorides is established.
