✦ Synopsis

Current transients have been measured for silver electrodes discontinuously scratched under potential control while immersed in 1 M KOH solutions. Formation of two distinct types of oxidised monolayer occurs in different potential ranges below the Ag-Ag,O reversible potential. Formation of the first monolayer of A&O is facilitated by an intermediate Ag(I) species at monolayer coverage, probably AgOH. The same phenomena are discernable in rapid potentiodynamic sweep and potentiostatic pulse

AImract--Galvanostatic experiments have been made on iron electrodes in hydrogen-poor and hydrogen-saturated alkaline solutions at 20°C. Emphasis was on the active behaviour of iron, but attention was also paid to its passivation. The mechanism of the anodic dissolution of active iron is found to b

Ag,O and AgO formed by potentiostatic oxidation of silver in O.lN KOH have been chemically analysed for the mean valency of silver ion. The anodic oxide formation proceeds in two stages and the silver ion in the oxide changes from Ag+ to Ag2+ at a transition potential. The reduction of AgO at consta
