This dissertation is written in two sections. The first section deals with the development of methods for the estimation of the effective electrolytic surface area of rough and porous silver electrodes in alkaline electrolyte. Data are presented comparing the results of three different methods of surface area estimation. Model pore electrodes were also prepared and oxidized to study the reactions in a pore. Data for constant current oxidations of these electrodes is given. The second section deals with the potentiostatic oxidations of silver in alkaline electrolyte. Data are presented on the total charge acceptance versus applied potential for a potential range that runs from the potential required to first produce silver (I) oxide to that required to evolve oxygen off the surface of the electrode. The shape of this plot indicates the formation of two types of silver (I) oxide. Three oxidation reactions were noted. The first was the formation of silver (I) oxide. The second was the formation of silver (II) oxide. The nature of the third reaction is not yet known; however, some evidence indicates it is the formation of silver (III) oxide.
