The pH meter is an accurate and easy-to-use device for determining the pH of a solution. You will be using a pH electrode attached to the LabQuest2 interface and computer as a pH meter in this experiment. WebThe negative sign assures that pH of most solutions, except extremely acidic ones, is always positive. It is fortuitous that the potential of the glass electrode (Eq. 4) is also a logarithmic func-tion of hydronium activity; therefore, the potential of the glass electrode is a linear function of pH Eglass electrode= E’ – RT/2.303F pH (6) rcbo wiring
