pH Measurement Fundamentals
The measurement of pH of aqueous solutions are generally using a glass electrode as the
indicator electrode, calomel electrode as the reference electrode, when the hydrogen ion
concentration in the solution (strictly speaking, activity) that the pH value of the solution is changed,
a glass electrode and a calomel electrode generated between the electric potential also changes with
the potential change relationship meets the following formula:
E = -58.16 ×  pH × (273 t ℃) / 293 (mV)
E: represents the electric potential changes in millivolts. (MV)
pH: the changes of the pH of the solution.
t: indicates the measured solution temperature ℃.
