## A&met-Electrochemical properties of ruthenium, particularly the anodic evolution of oxygen and anodic dissolution of ruthenium have been investigated by means of polarization measurements and product analyses. The electrode surface gradually colours black during oxygen evolution. This is due to

Attstrae-The polarization curves of oxygen evolution and reduction at platinum electrode were obtained in diluted aqueous solutions of sulfuric and perchloric acids in the temperature range 2&325"C. The Tafel slopes of polarization curves of oxygen evolution are practically independent of the temper
A&act -Kinetic parameters were determined for the oxygen evolution reaction on 50-50 atom percent alloys of Ru-Ir, Ru-Pt, and Ir-Pt and compared with results obtained using ruthenium, iridium, platinum, and RuO,,TiO, electrodes. The potentiostatic studies were made on oxide covered electrodes at 80Β°
The results given in Part I of this series are analysed quantitatively. From the resistance change of a platinum film electrode during cathodic and anodic polarization in lo-' N sulphuric acid solutions, the following results emerge. (1) The rate constant and activation energy of the desorptive co
