An amphoteric substance can act both as an acid and a base. That is, an amphoteric substance can donate protons and also accept protons. C O X 3 X − 2 does not have any protons so it cannot act as an acid. It is the conjugate base of H C O X 3 X −. H P O X 4 X − 2 is the conjugate base of H X 2 P O X 4 X −. damascus steel large folding knives
