AbstractTheoretical and practical aspects of square wave conductometry are discussed. Equilibrium conditions for a simple bridge circuit are compared with those for classical sine wave conductometry. It is shown that square wave conductometry is less dependent on the choice of the cell parameters.As an example, square wave conductometry is applied to the titration of hydrochloric acid and acetic acid with sodium hydroxide, using both wire and plane electrodes. The influence of the presence of a redox couple upon the equilibrium condition appears to be negligible in square wave conductometry.
