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. | *Final composition* || | 190.2 mM | Sodium (Na<sup>+</sup>) | | 11.0 mM | Potassium (K<sup>+</sup>) | | 37.8 mM | Ammonium (NH<sub>4</sub><sup>+</sup>) | | 0.09 mM | Calcium (Ca<sup>2+</sup>) | | 0.83 mM | Magnesium (Mg<sup>2+</sup>) | | 0.033 mM | Iron II (Fe<sup>2+</sup>) | | 38.0 mM | Chloride (Cl<sup>-</sup>)| | 0.87 mM | Sulfate (SO<sub>4</sub><sup>2-</sup>) | | 106.1 mM | Phosphate (PO<sub>4</sub><sup>3-</sup>) | | 50.0 mM | Lactic Acid| -- Main.AurkoDasgupta - 03 Jun 2013
