where R is the molar gas constant, F is the Faraday constant, and T is the absolute temperature. A potential of 61.5 mV will be developed for every pH unit difference between the known solution within the measuring electrode (pH 6.840 buffer) and the sample solution at 37 °C. A potential difference of zero indicates that the pH values of the unknown and known solutions are equal. A potential difference of 33.5 mV will add 0.544 pH units to the known value, resulting in a pH of 7.384 for the sample solution.
