WebSep 12, 2024 · A solid electrode can replace a mercury electrode for many voltammetric analyses that require negative potentials, and is the electrode of choice at more positive potentials. Except for the carbon paste electrode, a solid electrode is fashioned into a disk and sealed into the end of an inert support with an electrical lead (Figure 11.4.3 ). WebFactors Involved in Potentiometric Measurement of pH. Several factors affect measurement through a pH meter, such as. Temperature: The measurement of pH, voltage signals, …
