Preferred Label : filling solution;
Detailed label : filling solution of a reference electrode;
IUPAC definition : Solution containing the anion to which the reference electrode of the operational
pH cell is reversible, e.g. chloride for silver-silver chloride electrode. In the
absence of a bridge solution, a high concentration of filling solution comprising
cations and anions of almost equal mobility is employed as a means of maintaining
the liquid junction potential small and approximately constant on substitution of
test solution for standard solution(s).;
