  1. 1. Analysis of Chemistry Paper 3 2011Johor• Rusting• Titration in neutralization• Plan a laboratory experiment to investigate the different pairs of metal produce different voltage of a voltaic cell.Kedah• Position of metals in the reactivity series• Plan a laboratory experiment to investigate the role of water in showing the properties of acid. (use distilled water and dry propanone as solvents )Kelantan• Electrical conductivity of three compounds in their molten state• Prepicipitation of sliver chloride• Plan a laboratory experiment to investigate the effect of metals on the rusting of iron.Melaka• Heat of combustion for alcohols• Plan a laboratory experiment to investigate the effect of acid and alkali on the coagulation of latex.Negeri Sembilan• Heat of displacement of copper from its salt solution• Concentration of hydroxide ions and the pH value of ammonia solution• Plan a laboratory experiment to differentiate the two hydrocarbons. ( hexane, hexane)Pahang• The solubility of salts in water
  2. 2. • Heat of combustion of alcohols• Plan a laboratory experiment to investigate the effect of metals on the rusting of iron.Perak• Effect of metal on rusting of iron• Determine the empirical formula of oxide of copper• Plan a laboratory experiment to identify the colourless liquids. ( hexane, ethanoic acid )Perlis• Compare the hardness of bronze with its pure metal, copper• Plan a laboratory experiment to compare neutralization between a named strong acid with sodium hydroxide and heat of neutralization between a named weak acid with sodium hydroxide solution.Sarawak• Effect of the size of a solid reactant on the rate of reaction• Reactivity of chlorine gas, bromine vapour and iodine vapour with heated iron wool respectively• Plan a laboratory experiment to investigate the effect of different metals in contact with iron on the rusting of iron.Sekolah Berasrama Penuh• Effect of the type of electrodes ( carbon & copper ) on the product formed during electrolysis• Plan a laboratory experiment to compare the heat combustion of methanol, ethanol and propan-1-ol.Terengganu• Heat of combustion of alcohols• Effect of metal on rusting of iron when it is contact with other metals
  3. 3. • Plan a laboratory experiment to construct the electrochemical series based on potential difference between two metal. ( copper II sulphate solution, magnesium strip, zinc strip, iron strip, lead strip and copper strip )
