WebpH measurement is a routine, yet one of the most important parameters of an analytical laboratory. Measuring pH although it is an effortless process, it can lead to errors if not … WebThe pH meter to which the sensor is connected needs to find a mathematical endpoint based on the change in millivolt signal per a time unit. Since the change in millivolt signal is derived from the interaction of the hydronium in solution with the sensing glass of the sensor, protein contamination can have an effect on the value, introducing ...

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
