- 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.
