Feb 18, 2021· 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.
Details 
1) Anhydrous phosphoric acid can be obtained in colourless crystals. a) Melting Pt. = 42.35oC. 2) Commercial grades of phosphoric acid contain 50-90% of acid. 3) It is found in syrupy form when concentration is about 85%. 4) At 250oC it decomposes producing pyrophosphoric acid. On further heating metaphisphoric acid. or Glacial phosphoric acid.
