  • 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      • Any chemical compound formed from an acid where the H+ ion has been replaced by a metal or other positive ion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
