Appendix 3 Barium and Barium Salts Spacecraft Water

Barium (Ba) salts have a range of solubilities in water. Ba metal is insoluble in water but soluble in alcohol. The three least soluble Ba salts are the sulfate, the carbonate, and the sulfide. The acetate, the cyanide, the chloride, and the nitrates and alkaline salts, such as the oxides and
