- Acids, Bases and Salts
- Acid
- Proton donor
- Gives off H+ ions in solution
- HCl (hydrochloric acid), H2SO4 (sulphuric acid), HNO3 (nitric acid)
- Base
- Proton acceptor
- Alkali
- Soluble base
- Gives off OH- ions in solution
- NaOH (sodium hydroxide), KOH (potassium hydroxide), NH3 (aqueous ammonia)
- metal oxides, metal hydroxides and ammonia
- Salt
- Any chemical compound formed from an acid where the H+ ion has been replaced by a metal or other positive ion
- Anhydrous - compound containing NO water molecules
- Hydrated - chemical compound containing water molecules
- Water of crystallisation - water molecules that form part of the crystalline structure of a compound
- acid + alkali -> salt + H2O
- acid + metal -> salt + H2
- acid + metal oxide -> salt + H2O
- acid + carbonate -> salt + H2O + CO2
- Acid
