A"continuous weighing"procedure is employed in studying the behaviour of the Ag electrode in 40% KOH solution.The Ag electrode is weighed continuously during the constant-current charging and discharging processes,and the weight-time curves so obtained show 4 straight-line regions corresponding to the 4 stages of the charging and discharging curves(see fig.3)From the slopes of these straight lines a probale reaction mechanism is proposed for the anodic oxidation and cathodic reduction of Ag.A single oxidation of Ag to Ag_2O o(?)currs in the 1st stage and both the oxidation of Ag_2O to AgO and that of Ag straight forward to AgO take place simultaneously during the 2nd stage of the charging process.In the discharge process,the 1st stage is due to the reduction of AgO to Ag_2O and the rcaction Ag+AgO→Ag_2O in parallel,while the reduction of Ag_2O toAg accounts for the 2nd stage.Quite possibly,this latter reaction is accompanied by the direct reduction of some AgO to Ag.Our results indicate that this"continuous weighing"procedure is a simple but useful method in studying electrode processes not involving gas-evolution.However,the theorectical slopes presented in this paper have been based on assumed specific gravity of the solution in the electrodes immediate neighbourhood using densities of Ag_2O(7.143)and AgO(7.44)taken from rather old literature The reliability of this value of 7.44 for AgO is questionable.Hence,a more thorough investigation of the reaction mechanism has to wait for more reliable values of the densities of the silver oxides.Further work is being planned in this direction.The origins of the phenomena of losing weight during the initial period and the bending off of the curve at the end of the charging process are not yet established.Some probable explanations have been propounded.
