  • acid is a proton donor
  • an acid is a substance which produces hydrogen ions when dissolved in water
  • an oxide is a compound or molecule that contains the element oxygen
    the oxygen can be bounded to either a metallic element or a non-metallic element
  • acidic oxides- oxide of a nonmetal eg. CO2, SO2, NO2
  • acidic oxides react with bases to form salt and water
  • when acidic oxides dissolve in water they produce an acidic solution
  • when acidic oxidies dissolve in water they produce an acidic solution
  • basic oxides are oxides of a metal eg. Na2O, MgO, CaO
  • basic oxides react with acids to produce salt and water
  • when basic acids are dissolved in water they produce a basic solution
  • amphoteric oxides are oxides of the metals lead (Pb), aluminium (Al) and Zinc(Zn) eg. PbO, Al2O3, ZnO
  • amphoteric oxides react with both acids and bases
  • neutral oxides are oxides of nonmetals eg. NO (nitrogen monoxide), CO (carbon monoxide)
  • neutral oxides do not react with acids or bases
  • an indicator is a chemical used to determine the end point of a neutralisation reaction as well as differentiate an acid from an alkali
  • universal indicator solution is a mixture of indicators that change colour in the presence of different types of substances
