Abstract
Measurements were made of the effect of pressure on the rate of dissolution of Mg at pH 2.0 in two concentrations of aqueous MgCl2. The induction period of the reaction was studied in detail with a sensitive gas-measuring technique. X-Ray diffraction patterns of insoluble reaction products were examined. Univalent magnesium is an essential intermediate, the rate being controlled by H2 bubble growth through the gelatinous Mg(OH)2 film, which remains on and protects the surface in 0.3 molal solution, and by bubble nucleation in 3 molal solution, in which the film is complexed away.
