Most acids react with metals, metal oxides, hydroxides, hydrogencarbonates, and carbonates. All these reactions produce a salt which is a compound of an anion and a cation.
Acid + Hydroxide → Salt + Water
Acid + Metal oxide → Salt + Water
Acid + Metal → Salt + Hydrogen
Acid + Carbonate → Salt + Water + Carbon dioxide
Acid + Hydrogencarbonate → Salt + Water + Carbon dioxide
Metal oxide + Water → Base (Metal hydroxide)
Non-metal oxide + Water → Acid
Amphiprotic
A species that can act as both a proton donor and a proton acceptor. Anything amphiprotic is also amphoteric.
Conjugate base
A Bronsted-Lowry acid that has donated a proton
Amphoteric
