Abstract: An embodiment provides a method for measuring an alkalinity of an aqueous sample, including: introducing an aqueous sample to a voltammetric pH electrode; holding the potential of a voltammetric pH electrode at a pH end point potential; applying a voltage step waveform comprising at least one potential pulse to the voltammetric pH electrode; titrating the aqueous sample; and measuring a current output resulting from the voltage step waveform, wherein the measuring comprises square wave amperometry. Other aspects are described and claimed.
