  • Neutralisation is a chemical change.

  • A salt is a type of chemical that is related to an acid and is usually made from acids.
  • Sodium Carbonate (Na2CO3) is added to ethanoic acid to neutralise it.
  • It takes 20cm3 of Sodium Carbonate to produce a pH of 7
  • Limewater is used tot test for carbon dioxide.
  • A reaction produced bubbles of carbon dioxide (CO2) gas. How would you identify the gas?
    Bubble the gas through limewater. The limewater turns milky white.
