title: Composition of Aqueous Solutions in Equilibrium with Sulfides and Oxides of Iron at 350{degrees}C.
abstract: Solutions of potassium chloride (pH-buffered and 1-molal) equilibrated at 350 degrees C with pyrrhotite, pyrite, and magnetite contained approximately 1 millimole of reduced sulfur and less than 0.1 millimole of oxidized sulfur per kilogram. Similar solutions equilibrated with pyrite, magnetite, and hematite contained approximately 1 millimole of reduced sulfur, but 3 to 6 millimoles of oxidized sulfur per kilogram. Both types of solutions contained less than 0.1 millimole of iron per kilogram at pH >/= 6 and approximately 100 millimoles per kilogram at pH 2.
