-
The secondary differential oscillographic chronopotentiometric titration has been carried out for Ca, Mg, boric acid and phenic acid determenition. The incision on the d2E/dt2-E curves produced by the depolarizers is more sharp than that on the dE/dt-E curver. Theindication of the end point of titration has been greatly improved.
