Effect of an industrial expander on the discharge process of a lead microelectrode in 4.5M sulphuric acid

  • 26 Accesses

  • 9 Citations

Abstract

The presence or absence of an industrial expander is shown to produce a difference in the discharge of a lead microelectrode in concentrated sulphuric acid. The expander acts both before and after passivation, and modifies the concentration and relaxation time of Pb(II) soluble reaction intermediates.
