Anodic Behavior of Iron in H[sub 2]SO[sub 4]

Various phenomena associated with the steady state of the cell Fe | H 2 SO 4 ( 2 N ) | Pt are discussed with particular emphasis on the factors governing reproducibility. The formation of a brownish, gelatinous coat is observed, but its significance is obscure and it appears to have no direct effect upon transients produced by short off‐times. An empirical equation has been found which represents the short off‐time transients over a relatively wide voltage range. A discussion is given of the principal points that must be embodied in a theory describing the transient behavior of the cell. The part played by the charging of the usual double layer is demonstrated to be of little consequence in the observed transients.
