  • Acids, bases and salts. c2.2.5
    • Acids
      • Is a substance with a pH less than 7.
      • Form H+ ions in water.
    • State symbols
      • (s) - solid
      • (l) - liquid
      • (g) - gas
      • (aq) - aqueous - dissolved in water.
    • Bases
      • Is a substance with a pH greater than 7
      • An Alkali is a base that dissolves in water.
        • Alkalis form OH- ions in water.
        • Acid + Base = Salt + water
          • H+ + H- = H20
          • Acids
            • Is a substance with a pH less than 7.
            • Form H+ ions in water.
      • Acids and Bases neutralise each other.
      • Acids reacting with metals.
        • Acid + Metal = Salt + Hydrogen
        • Acid + Metal Oxide = Salt + Water
          • These are neutralisation reactions.
            • Acid + Metal Hydroxide = Salt + Water
        • Acid + Metal Hydroxide = Salt + Water
      • Making salts
        • You can make soluble salts using a metal or an insoluble base.
        • You can make soluble salts using an alkali.
        • Making insoluble salts - Precipitation reactions.

    This is really good thanks although Acid + Metal Carbonate = Salt + Water + Carbon Dioxide is missing
