asymmetry potential

of a glass electrode
The measured potential difference of a symmetrical cell with identical solutions and reference electrodes on each side of the glass @[email protected] There is rarely the need, nor the possibility, of measuring the @[email protected] potential of commercial glass electrodes. Drifts in glass electrode potentials with time and variations from @[email protected] to @[email protected] in the potential measured in a standard buffer may be attributed to changes in @[email protected] potential.
