The functional constraints are that Calcium Chloride cannot be autoclaved in the presence of sulfates, or it will precipitate as calcium sulfate. Ferrous sulfate when autoclaved will decompose to ferric sulfate, ferric oxide and sulfur dioxide. This means that either calcium chloride OR magnesium sulfate may be added before autoclaving, but not both.
