Phosphate Rock Properties
Properties of Phosphate Rocks. Anhydrous phosphoric acid forms prismatic crystals, which readily deliquesce in the air. As ordinarily prepared, concentrated phosphoric acid is a clear, colorless, syrupy liquid (specific gravity, 1.83), which attacks most metals and bases, forming the corresponding phosphate salts.
