amphoteric means it can react as an acid but also as a base.

Answer 7

ok so how do we apply it?? like in chem

Answer 8

@thomaster not trin to be rude but r u replying cause im on os cause of this :)

Answer 9

You can let a base react with an acid and reversed
but when you have an amphoteric metal, you can let it react with both.

For example, \(MgO + HCl \to MgCl_2+H_2O\)
In this case, \(MgO\) is the base and \(HCl\) is the acid.
You can't let \(MgO\) react with a base.

Now the second example \(ZnO+2H^+\to Zn^{2+}+H_2O\)
In this case, \(ZnO\) is the base and \(HCl\) is the acid.
But \(ZnO\) can also react with a base:
\(ZnO+2OH^-+H_2O\to [Zn(OH)_4]^{2-}\)

That means Zn (zinc) is an amphoteric metal.
Other examples of amphoteric metals are aluminium, beryllium, lead and tin.

Answer 10

Sorry not HCl but H+ is the acid in the second example :P
