It is then connected to a reference electrode (calomelelectrode), to form a galvanic cell. The cell is then connected to the potentiometer and its Ecell is determined. When the emf is plotted against the volume of K2Cr2O7 added, a cure of the type shown in figure 1.14 is obtained. The end point is the point, where the slope of the curve is maximum. ................
