relationship between the mass of magnesium and mass of oxygen once the magnesium has been heated and reacted with the oxygen. There will be 3 variables in this experiment. The independent variable will be the mass of magnesium ribbon as different measurements will be taken and used for each trial. The dependant variable will be the mass of Magnesium Oxide‚ this is a measured variable as the mass of oxygen can be calculated and will enable us to determine the formula for Magnesium Oxide. The controlled variable

EXPERIMENT 4 Title: Preparation of magnesium sulphate. Date:11.02.2010 Aim: To prepare magnesium sulphate Theory: Magnesium sulfate (or magnesium sulphate) is a chemical compound containing magnesium‚ sulfur and oxygen‚ with the formula MgSO4. In its hydrated form the pH is 6.0 (5.5 to 6.5). It is often encountered as the heptahydrate‚ MgSO4·7H2O‚ commonly called Epsom salt. Anhydrous magnesium sulfate is used as a drying agent. Since the anhydrous form is hygroscopic (readily absorbs water

ANTACIDS- Classification and Mechanism of Action INTRODUCTION Antacids are defined as a substance‚ generally a base‚ which counteracts stomach acidity. The name antacid means anti-acid (against acid). Antacids are the primary treatment for ailments such as gastric reflux‚ gastritis‚ upset stomach and heartburn. Hydrochloric acid is secreted by the stomach to kill harmful organisms‚ aid digestion and activate digestive enzymes. Excess secretion of acid into stomach or impaired resistance by

Finding the formula of magnesium oxide Aims When magnesium is heated in air‚ it reacts with oxygen. During this oxidation reaction‚ magnesium oxide is produced. This increases the mass. If we know the mass of magnesium at the start‚ and the mass of magnesium oxide produced at the end‚ we can work out the mass of oxygen which has been combined with the magnesium. We can use these masses to work out the formula of magnesium oxide. Eye protection must be worn Apparatus Crucible and lid

of this lab was to test the law of definite proportions for the synthesis reaction of combusting magnesium. In this lab‚ the polished magnesium ribbon was placed in covered crucible and was heated in order for it to react with Oxygen presented in air and in water provided. The result showed that Magnesium oxide formed through chemical reaction was made up of 60.19% magnesium and 39.81% oxygen‚ which is approximate proportion of both particles in every Magnesium oxide compound. From this lab it can
