Formula: H3PO3
Calcium is Ca. Phosphorous acid would be H3PO3. However, the name "calcium phosphorous acid" taken as a whole makes no sense. and if "phosphorus acid" was not a simple misspelling, THAT name makes no sense either.
The chemical formula for boron is B, while the chemical formula for phosphorus is P.
The empirical formula for phosphoric acid is H3PO4. Its molecular formula is P2O5·3H2O. It is composed of the elements hydrogen, phosphorus and oxygen. Most solutions of phosphoric acid are composed of some amount of H3PO4 in water, H2O.For more information about phosphoric acid, see the Web Links to the left.
The chemical formula for phosphorus triiodide is PI3.
The chemical formula for phosphorus hydrogen is PH3.
