Web1 Answer. 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 −.

If both are true, then I have an amphoteric substance. In proofreading this answer, I realize I said I would restrict myself to aqueous systems, in which case using the Brønsted system may be more helpful. WebThe pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14.

If an acid is not listed here, it is a weak acid. It may be 1% ionized or 99% ionized, but it is still classified as a weak acid. Any acid that dissociates 100% into ions is called a strong acid. If it does not dissociate 100%, it is a weak acid. dave croft
