Answer 1

hey

dude

here is your answer

an amphotericcompound is a molecule or ion that can react both as an acid as well as a base. Many metals (such as copper, zinc, tin, lead, aluminium, and beryllium) form amphoteric oxides or hydroxides. Amphoterism depends on theoxidation states of the oxide. Al2O3 is an example of anamphoteric oxide.
