Phosphoric acid (orthophosphoric acid, monophosphoric acid or phosphoric (V) acid) is a colorless, odorless phosphorus -containing solid, and inorganic compound with the chemical formula H 3 P O 4. It is commonly encountered as an 85% aqueous solution, which is a colourless, odourless, and non- volatile syrupy liquid.

Phosphoric acid is a phosphorus oxoacid that consists of one oxo and three hydroxy groups joined covalently to a central phosphorus atom. It has a role as a solvent, a human metabolite, an algal metabolite, a fertilizer and a NMR chemical shift reference compound. It is a conjugate acid of a dihydrogenphosphate and a phosphate ion.
