The mineral pyrite, FeS2(s), can incorporate large amounts of arsenic. The dissolution of arsenic-rich pyrite can therefore release arsenic into groundwater (i.e., pyrite dissolution can be written as FeS2(s) = Fe2+ + S22-). What equation would you use to calculate whether pyrite in an aquifer will dissolve or precipitate?
