Metaphosphoric acid exists as a cyclic trimer, polymer or cyclic tetramer but not as a monomer. Resultantly, phosphorus acid, H 3 PO 3, is dibasic oxoacid of phosphorus because of the presence of two P-OH bonds, and the phosphoric acid, H 3 PO 4, is tribasic because of the presence of three P-OH bonds.
