Curve showing the effect of the pH of a solution of HCN in borax on the of frog skin. Period of exposure to cyanide represented as the time between arrows, at other times the skin was exposed to borax alone. pH values used were and Abscissas represents the exposure in minutes and the ordinates the in volts. There actually are fewer molecules of cyanide in a solution with a pH of than with a pH of (Fig. i). So if the molecules were the toxic units, it would be expected that there would be less stimulation and more toxicity when the solution contains the greatest number of molecules than under the reverse conditions of.
