An Attempt to Investigate the Reduction of Ruthenium Tetroxide by Potentiometric Methods

Abstract

The titration curve for osmium tetroxide is similiar to the one obtained for ruthenium tetroxide becauee there is a minimum on each curve and the potential increases with each addition of HCl. . . . Another point of interest is the fact that the voltage of the osmium tetroxide solution varied betweon rather large limits. This may be due to the oxidizing action of osmium tetroxide on the faint tracee bf impurties present in the water. It seems that if chemically pure water was used there ought to be no voltage detected. In each curve, no matter what the initial voltage was, for any definite amount of' HCl added to the solution the potential was almost the same. [From Conclusion]
