The boric acid content in the primary cooling system of light water reactors can be determined potentiometrically. In pressure reactors boric acid is used as a safety reserve when the reactor is switched off. In addition, boron is used to compensate the difference in reactivity and, more recently, for output regulation.

In the potentiometric determination of boric acid this is treated with a polyvalent alcohol. The complex compound formed behaves like a monovalent medium-strength acid and can be titrated with sodium hydroxide.
