“…The effect of the cell geometry on the uncompensated Ohmic drop due to solution resistance has been studied extensively in the past (see [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27] and references therein). It is clear from these reports that the geometry and placing of the Luggin-Haber capillary [28] is crucial in reducing measurement errors due to the inhomogeneous current density distribution, Ohmic resistance and shielding of the electrode by the capillary.…”

“…Of the two methods (8,9) most commonly used for cathodic potential determinations, the "direct" method was chosen. This method is simpler, and, 573 according to authoritative views (8,10), is as accurate and reliable as the "indirect" method, if applied correctly.…”

The absolute hydrogen overvoltage values of titanium in hydrofluoric acid increase, or the cathodic potentials, vii, decrease (become more negative) with addition of alkali fluorides to the acid. The vH decreases with increasing concentration of the salt in the sequence NH4F --~ KF ~ NaF, which is also the sequence of decreasing cationic radius. For example, at 50 ma/cm ~ ~H decreases from -0.8 v in pure 0.1N hydrofluoric acid to -1.68 v in the same acid if it is 1M with respect to sodium fluoride. If the titanium cathode dissolves in the acid, the wi-current density relationship is linear; if the dissolution ceases (at higher concentrations of the added fluoride), Tafel's relationship is fulfilled. In between there is a mixed straight line and quasi logarithmic relationship, the latter occurring at higher current densities. Organic colloid solutions of agar-agar or arabic gum appreciably decrease vii; methylene blue solutions increase it slightly.
