    • acid + base= salt + water
    • what dose soluble mean?
      It means that it is able to dissolve in water
    • alkali is an soluble
      base
    • base is an insoluble alkali
    • alkali's are metal hydroxides e.g magnesium hydroxide
    • bases are metal oxides e.g copper oxide
    • hydrochloric acid
      HCL
    • sulfuric acid
      H2SO4
    • nitric acid
      HNO3
    • Magnesium oxide + Hydrochloric acid
      Magnesium chloride + water
    • Copper hydroxide + Nitric acid=
      Copper nitrate + water
    • Potassium oxide + sulphuric acid=
      Potassium sulphate + water
    • Metal + Acid = Salt + Hydrogen
    • Magnesium + hydrochloric acid=
      magnesium chloride + hydrogen
    • Copper + nitric acid
      copper nitrate + hydrogen
    • Potassium + sulphuric acid
      potassium sulphate +hydrogen
    • Barium + nitric acid
      barium nitrate + hydrogen
    • Metal carbonate + acid = salt + water + carbon dioxide
    • Calcium carbonate + hydrochloric acid
      calcium chloride + water + carbon dioxide
    • potassium carbonate + hydrochloric acid
      potassium chloride + water + carbon dioxide
    • Magnesium carbonate + nitric acid
      magnesium nitrate + water + carbon dioxide
    • A displacement reaction is a chemical reaction which a more reactive element displaces a less reactive element from its compound
    • zinc + lead nitrate=
      zinc nitrate + lead
    • carbonate
      CO3
    • making salts from insoluble alkali
      1. Measure out 25cm3 of sulphuric acid and heat gently
      2. remove from hear and add copper oxide until no ore will dissolve and copper oxide is in excess
      3. the acid will have been used up now
      4. use a filter funnel and paper to filter off the excess copper oxide
      5. this will leave a blue solution of copper sulphate
      6. heat the solution in an evaporation basin to remove some of the water
      7. as the solution cools copper sulphate crystals will start to form
    • during neutralisation reaction (acid + alkali=salt + water), hydrogen ions (h+) from the acid react with hydroxide ions (OH-) from the base to produce water
