Abstract

PURPOSE:To obtain a beta-pH curve with the simplicity same as the ordinary titration operation by self-recording a buffer power beta with respect to pH after it is determined by an electric treatment of response of a pH electrode in a sample liquid with the titration of a strong acid or a strong base. CONSTITUTION:A sample liquid 4 containing ionogen is titrated with a strong acid or a strong base. For example, a voltage output of a pH meter equipped with a glass electrode 2 and a reference electrode 3 is amplified with an amplifier and an output of the time variation dE/dt thereof is obtained with a differentiation circuit. After the amplification of the output, an output is obtained with multiplying/dividing module in proportion to an inverse number dt/dE thereof. As the value dE is proportional to dpH, dt/dE is proportional to a dt/dpH. The output thus obtained is inputted to the axis Y of a XY recorder while the output of the pH meter is inputted to the axis X thereof as intact. In this manner, a relation curve between a buffer power beta and the pH is obtained as expressed by beta=dB/d'pH (beta represents the concentration with addition of a strong alkali).
