Manganese(III) solutions were prepared by known electrochemical methods in sulfuric acid, acetic acid, and pyrophosphate media. The nature of the oxidizing species present in manganese(III) solutions was characterized by spectrophotometric and redox potential measurements. Kinetics of oxidation of L
## Abstract Impedance and potentiodynamic polarization measurements show that the addition of nickel to superferritic 290 Mo alloys improves their resistance to the corrosion process in sulphuric acid and plays a disastrous part in hydrochloric acid. The chemical composition, thickness and depth pr
