ABSTRACT:
A method of determining the concentrations of at least two of plural kinds of known free acids and ions contained in a solution, wherein these known free acids and ions are known beforehand to be different from each other in temperature changes and conductivity changes which are to occur in response to a titrant. The method includes a step of generating a differential temperature curve and an electric conductivity curve, which are obtained from a thermometric titration and a conductometric titration respectively and are used complementarily so that an end point which is hardly ascertained by one method of titration may be ascertained by the other method.
