The Anodic Behavior of Cathodically Prepolarized Bright Platinum Electrode in Sulfuric Acid Solution

Abstract

The anodic charging curves of a cathodically prepolarized bright platinum electrode in 1 n sulfuric acid solution saturated with hydrogen have been studied by means of a mechanical oscillograph.The behavior of stage α′ for anodic polarizing c. d. can be explained on the assumption that its stage is due to the molecular hydrogen accumulated in the vicinity of the electrode during the cathodic prepolarization, and that the concentration of the accumulated hydrogen decreases in the same manner as the chemical reaction of first order.
