basic information

The potentiometric measurement method, including pH measurement using electrodes, is a widely used rapid and simple analytical technique around the world. The potentiometric measurement method requires an indicator electrode and a reference electrode. The indicator electrode experiences a potential change depending on the composition of the sample solution. The role of the reference electrode is to provide a constant potential that is as unaffected by the sample solution as possible. The measured potential U arises from the individual electrodes created by the indicator electrode and the reference electrode...
