Acid =
solution produces h ions when dissolved in water.
base =
substance reacts with H ions of acid to form salt and water. many metal oxides or hydroxides. If base soluble in water called alkali.
Salt =
formed when metal ion replaced the h ions in an acid.
acid + metal ->
salt + hydrogen
acid + carbonate ->
salt + carbon dioxide + water
acid + base (alkali) ->
salt + water
metal carbonate + acid ->
salt + carbon dioxide + water
alkali + acid ->
salt + water
All dilute sols of acids
contain H + (aq) and can behave as proton donors.
monoprotic acid
one mole of acid produces 1 mole protons, therefore called monoprotic acid. HCl, HNO3, CH3COOH
diprotic acid
one mole produces 2 moles protons
all bases react with proton donors, so
called proton acceptors.
Acid is said to have been
neutralised by the base.
