3.2. Potentiometric pH measurement with oxide covered W electrodes
The preparation of W electrode for potentiometric pH measurement
involves the formation of tungsten-oxide on the electrode
surface. In Section 3.2.1, the particularities of oxidation processes
during the formation of type A–D electrodes will be briefly summarized,
while in Section 3.2.2, the results of potentiometric pH determination
will be presented.
