* Giant ionic lattice. * Electrostatic bonds hold lattices together. * Structure is simple cubic. * Some ionic crystals contain water. * Known as water of crystallisation. * These crystals are hydrated. * Blue copper sulphate crystals are the pentahydrate crystals – CuSO4.5H2O * If there is no water of crystallisation then the ionic crystal is said to be anhydrous. Ionic substances in solution: * Many dissolve in water without difficulty. * Ions become surrounded

How fast is your reaction? Part 1 – How temperature affect the rate of reaction Chemical equation Magnesium + hydrochloric acid → magnesium chloride + hydrogen Mg + 2HCL → MgCl2 + H2 Graph Conclusion and questions 1. What factors/variables did you keep the same in this experiment? * We kept the same volume of hydrochloric acid (10 cm3) and the magnesium ribbon (5cm) because that way we could get a fair test experiment. We also repeated

CHAPTER 1 INTRODUCTION 1.1 Background of the Study Generally‚ Palm oil mill effluent (POME) contains high chemical oxygen demand (COD) and biochemical oxygen demand (BOD) which can pollute the environment ecosystem if it is not treated properly. The characteristics of fresh POME are that it is highly viscous liquid‚ brownish in colour and discharged at a temperature of 80-90oC. Moreover‚ POME is extremely poisonous with a very low pH between 3.5 and 4.2‚ high chemical and biological oxygen demand
