Explain what mphoteric means using H2S as an example?
Answer:
In general, amphoteric means that a substance can behave as an acid or a base. So in this case H2S can lose a proton to become HS- (an acid behavior) or accept a proton and form H3S+ displaying a base behavior
"Amphoteric" means that the chemical in question is capable of functioning as both an acid and a base. It can react either way.
It will dissociate in water, into H+ and HS-, so that's how it acts as an acid, though I believe it is only weakly acidic.
I'm not sure of a reaction where it acts as a base, though I do know that is the definition of Amphoteric.
Amphoteric means that a molecule can accept a proton or it can donate a proton. H2S can accept a proton to become H3S+ or it can donate a proton to become HS-.
