Mikhail Usanovich developed a number of theories and proved a number of facts, such as: • Quantitative solution theory; • Equations of non-colligative properties of solutions and their dependence on composition; •
Generalized theory of acids and bases; • The so-called anomalous electrical conductivity Is a rule rather than an exception; • The
law of dilution is wrong for most solutions; • Systems where chemical interactions occur at equilibrium concentrations. == Bibliography ==
