In chemistry, an amphoteric compound (from Greek amphi- 'both') is a molecule or ion that can react both as an acid and as a base. What exactly this can mean depends on which definitions of acids and bases are being used. One type of amphoteric species are amphiprotic molecules, which can either donate or accept a proton (H ). This is what "amphoteric" means in Brønsted–Lo… WebA barium nitrate, silver nitrate B sodium chloride, barium nitrate C sodium nitrate, barium chloride D sodium sulphate, barium chloride Sodium, aluminium and sulphur are in the same period of the Periodic Table.
