REGULARITIES IN ELECTRICAL CONDUCTIVITY OF AQUEOUS SOLUTIONS OF SOME INORGANIC ACIDS

The concentration and temperature dependences of the specific electric conductivity (EC) of aqueous solutions of HCl, HBr, HNO3, HClO4, H2SO4 and HBF4, H2SiF6, and H2TiF6 were analyzed. It was shown that at a temperature of 298 K maximum specific EC of solutions of acids does not exceed the value of the limit high-frequency EC of water. The an-alytical equation allowing on the basis of maximum EC and corresponding to it concentra-tion to calculate the EC of acid solutions in a wide range of concentrations and temperatures was obtained.

Key words: specific conductivity, aqueous solutions, inorganic acids
