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