  • Acids, Salts and Bases
    • Acids
      • A species which is a proton donor
    • Salts
      • Produced when hydrogen ions in an acid are wholly or partially replaced by metal or ammonium ions
      • Can be produced by  neutralising acids with
        • Bases
          • Acids react with bases to form H20 and Salt
          • Solid base e.g CaO , will dissolve
          • Exothermic reaction
        • Carbonates
          • See bubbles of CO2
          • Acids react with CO3 to form H2O CO2 and salt
          • In a reaction the carbonate disappears into the solution
  • Acids
    • A species which is a proton donor
  • Hydrochloric acid - HCl
    • Sulfuric acid H2SO4
      • Nitric acid - HNO3
    • Sulfuric acid H2SO4
      • Nitric acid - HNO3
      • When an acid is added to water the acid releases H+ ions into solution

          • Alkalis
            • Release OH- ions into aqueous solution
              • NaOH(aq) --> Na+(aq)  + OH- (aq)

        • soluble bases
          • H+(aq) + OH-(aq) --> H2O(l)
            • neutralise acids
