ABSTRACT
Conductometric techniques enable the determination of concentrations on the basis of the connection between the conductivity and the ion concentration of solutions. In electrolyte solutions, electric conduction is brought about by the migration of ions. The conductivity of solutions is determined by the number and migration rate of the ions. The conductivity of solutions is, at a given temperature, in a given solvent and at a given concentration a parameter characteristic of the system under test. Conductometric measurements are carried out with low-frequency current, the frequency being lower than a few thousand hertz. The advantage of oscillometry over conductometry is that no galvanic contact is necessary between the solution and measuring device; thus the effect of polarization and other unwanted phenomena can be eliminated.
