n would be expected to increase as the ratio of inductorto acceptor increases; i.e. with increasing amounts of glucose.In such a case the vertical distance between the two curves wouldbecome greater and greater as we proceed across the diagram fromleft to right. As a matter of fact no such a tendency is observedthe curves remaining nearly parallel throughout their whole lengthand even tending to approach each other. We therefore concludethat there is no evidence of an induced reaction in this case. 12.

U. OF I. S. 5. FORM 3 54 \ r 13. potassium permanganate (actor) and potassium Sulfocyanide (inductor) Carried on a series of titrations with varying amounts of approximately M/10 KMn04 and KCNS solutions, with and without the presence of 5cc glucose solution (.25 gm. per 100cc solution). The KCNS was placed in a flask; to this was added 20cc(1-5) H0So. and an excess of KMnO^, together with the glucose solution. This was allowed to stand at room temperature for thirty minutes and then the excess KMn04 was titrated back with KCNS. The amounts of KCNS and KMnO used, with and without the 4 presence of glucose, were plotted against each other. The verticaldistance between the two curves represents the amount of KMnO^used by the glucose in the presence of KCNS. The curves run almostparallel to each other, leading us to conclude the the KCNS didnot induce the oxidation of the glucose by the KMnOA• cc cc KMnO.4 KCNS 5.1 5.1 5 5 10.2 10.2 10 10 15.4 15.3 15 15 20.4 20.4 20 20 25.5 25.5 25 25
