Re: What makes something amphoteric?
amphoteric substances react with both acids and bases.
i.e. Al2O3
Al2O3 + 6HCl --> 2AlCl3 + 3H20
in this reaction, aluminum chloride reacts with an acid, HCl
2NaOH + Al2O3 + 3H2O --> 2Na[Al(OH)4]
in this reaction, aluminum chloride reacts with a base, NaOH

Re: What makes something amphoteric?
Amphoteric compounds have both basic and acidic character so they can act as either an acid or a base in a reaction, in comparison to a lot of molecules that are labeled as either an acid or base.

Re: What makes something amphoteric?
Compounds that demonstrate both acidic and basic properties, and can act as either an acid or a base are charactarized as amphoteric. Metal oxides as well as hydroxides are examples of amphoteric compound, with its acidic or basic nature being in respect to their oxidizations.

Re: What makes something amphoteric?
H2O is amphoteric because it can be an acid or base. This means is can either accept an electron or donate an electron.
Re: What makes something amphoteric?
something that is amphoteric has both basic and acidic character, which means it can accept an e- pair or donate one. Water is a common amphoteric substance
