title: Modified reverse pulse polarographic behaviour of magnesium ion in aqueous solution.
abstract: Modified reverse pulse polarography (MRPP) is proposed for measuring the quantity of a reduction product formed at the initial potential in reverse pulse polarography. A double potential-step method is employed for this purpose. MRPP has been applied to the study of the electrochemical behaviour of magnesium in aqueous solution. For magnesium the height of the MRPP anodic wave was proportional to concentration at low pH, but not in unbuffered neutral solution. This difference is attributed to formation of hydroxo-magnesium complexes because of depletion of hydrogen ions near the electrode in a neutral solution.
