The Effects Of Ultrasonic Vibration, Tension And Torsion On The Charge Acceptance Of The Alkaline Silver Electrode ; Ii. Potentiostatic Studies Of The Oxide Growth Rate Law For The Alkaline Silver Electrode ; Iii. The Determination Of Ionic Transport In Silver Oxide Using Radiotracer Techniques With Ag[Superscript 110m], Reed Harold Chase
Theses and Dissertations
The effect of ultrasonic vibration on the anodic oxidation of silver foil in KOH was studied. An increase in charging capacity of approximately 20% was found to be the result of cavitation erosion. Silver wire was exposed to tension and torsion during oxidation but no change in charge acceptance was caused by these stresses. The oxide growth rate on silver foil electrodes was compared to rate equations that have been proposed for other metals. Uhlig's equations for the growth of semiconductor oxides was found to describe most of the data. The data did not fit other rate equations. Determination of …
Voltammetric And Electrochemical Kinetic Studies Of The Halides And Halogens At A Platinum Rotating Ring-Disk Electrode In Anhydrous Acetic Acid, Donald Harrison Cranney
Voltammetric And Electrochemical Kinetic Studies Of The Halides And Halogens At A Platinum Rotating Ring-Disk Electrode In Anhydrous Acetic Acid, Donald Harrison Cranney
Theses and Dissertations
The electrochemical behavior of the iodine-iodide couple was investigated in both basic and neutral acetic acid solutions at a platinum rotating ring-disk electrode. Voltammetric curves were obtained and discussed. Various kinetic parameters were determined and by comparing to theoretical kinetic parameters a probable reaction mechanism was deduced. The mechanism that best fit experimental results is the following I- + S = I(S) + e- I(S) + I- = I2 + S + e (slow). The electrochemical behavior of bromine, bromide, and chloride was also investigated in the same media. Voltammetric curves were recorded and discussed with emphasis on the hysteresis …
Estimations Of The Effective Electrolytic Surface Area Of Rough And Porous Silver Electrodes ; Ii. Potentiostatic Oxidation Of Silver In Alkaline Electrolyte, James Glenn Bearss
Estimations Of The Effective Electrolytic Surface Area Of Rough And Porous Silver Electrodes ; Ii. Potentiostatic Oxidation Of Silver In Alkaline Electrolyte, James Glenn Bearss
Theses and Dissertations
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 …
