Thus while curve I (Fig. 13) shows that an iV/20 solution of KCl nearly fits a para- bola, a similar solution of KI (Curve II) is too steep in its ascending portion; its maximum is lower than that for KCl and corresponds to a larger value of E; beyond the maximum it gradually approaches and merges into the KCl graph. Accord- ing to the simple Helmholtz view, the mercury in its natural state ought to be higher in potential than the KCl solution by. an amount represented by OP, about volt; but higher than the KI solution by OQ, about volt. Now if this were so we would expect to find that a cell containing these two solu- tions with a mercury electrode in each would give a of volt; but it is known that the is much smaller than this. If then we assume that because the curve is "normal" for KCl there really is a of volt between mercury and KCl in the natural state, we must admit from the evidence of the cell just mentioned that the mercury must also in the natural state be above the KI solution by practically the same amount. Hence, at the maximum state for the latter solution (represented by Q), when according to Lippmann's result the.
