Phosphoric acid
Phosphoric acid is produced industrially by one of two routes, wet processes and dry. In the wet process, a phosphate-containing mineral such as calcium hydroxyapatite and fluorapatite are treated with sulfuric acid. Ca5(PO4)3OH + 5 H2SO4 → 3 H3PO4 + 5 CaSO4 + H2O Ca5(PO4)3F + 5 H2SO4 → 3 H3PO4 + 5 CaSO4 + HF
