   • Water
   • Dilute Hydrogen Carbonate solution
     
     1. B. Studying the properties of acids and bases (HCl & NaOH) on the basis of their reaction with:
   • Litmus solution (Blue/Red)
   • Zinc metal
   • Solid sodium carbonate
2. Performing and observing the following reactions and classifying them into:
   A. Combination reaction
   B. Decomposition reaction
   C. Displacement reaction
   D. Double displacement reaction
   1. Action of water on quicklime
   2. Action of heat on ferrous sulphate crystals
   3. Iron nails kept in copper sulphate solution
   4. Reaction between sodium sulphate and barium chloride solutions
3. Observing the action of Zn, Fe, Cu and Al metals on the following salt solutions:
   • \(ZnSO_4\)(aq)
   • \(FeSO_4\)(aq)
   • \(CuSO_4\)(aq)
