C % by wt. C % by wt. C % by wt. C % by wt. C Concentration Curves The concentration curves of many substances show a maximum. This means that if the substance concentration continues to increase and the temperature remains constant, the conductivity will drop. The curve is temperature-dependent. For sulfuric acid, the position of the maximum concentration shifts in dependence on the temperature. Near the maximum (or near the minimum as for sulfur), the curve is so flat that the conductivity hardly changes over a large concentration range. This means that practical concentration determination is only possible in some areas: In the shaded areas of the concentration curves no concentration calculation is possible. Due to the ambiguity of the curves (the same conductivity may correspond to several concentration values), the measuring range of the concentration must be defined. Specifications 14–13
