- 3 H2SO4(l) + Ca3(PO4)2(s) + 6 H2O(l) 2 H3PO4(s) + 3 CaSO42H2O(s) Pure anhydrous phosphoric acid is a white solid that melts at 42.
- Phosphoric acid is prepared commercially by heating calcium phosphate rock with sulfuric acid; purer grades may be prepared by treating red phosphorus with nitric acid.
- The majority of phosphoric acid is manufactured using this process.

- At room temperature, phosphoric acid is a crystalline material with a specific gravity of 1.
