active ions is lower than expected. This leads to the pH definition pH = -log a H+ <4> 1.2 HOW TO MEASURE pH An electrochemical cell for pH measurement always consists of an indicating electrode whose potential is directly proportional to pH, a reference electrode whose potential is independent of pH, and the aqueous sample to be measured.
