Abstract

Abstract

The species of the trivalent ions of chromium in the HCl containing systems have been studied. The proper electroactive species was found to be[Cr(H₂O)₆]³⁺. The electrodepostion of chromium was found to be strongly affected by the pH of the bath due to the different species of trivalent chromium at different pH, and coordination compounds of Cr³⁺ with HCOOH or(NH₂)₂CO were not found.
