One of the most exciting and ambitious home-chemistry educational projects. Please choose a different one. Students will need the mass of the magnesium and the mass of oxygen which has combined with it. Burning magnesium in a crucible is a great experiment for explaining several concepts: differences between elements and compounds. Mixtures of magnesium with various oxidizers (barium nitrate Ba(NO3)2, potassium chlorate KClO3 or potassium permanganate KMnO4) were used as a photographic flash because photoplates back then were very sensitive to ultraviolet. Solid fuel provides just enough. Students weigh magnesium and heat it in a crucible. To find the formula of magnesium oxide, students will need the mass of the magnesium and the mass of the oxygen. Do not allow chemicals to come into contact with the eyes or mouth. When the magnesium metal burns it reacts with oxygen found in the air to form Magnesium Oxide. Oxygen is a colourless, odourless gas. Particular attention should be paid to the safe handling of acids, alkalis and flammable liquids. Burning metals in air, Magnesium oxide. Turn off the Bunsen burner and allow the apparatus to cool. Do not attempt to extinguish the solid fuel and magnesium — let them burn down completely. The burning ribbon should be held at arm’s length. The ratio should be close to 1:1 as the formula of magnesium oxide is MgO. Each activity contains comprehensive information for teachers and technicians, including full technical notes and step-by-step procedures. Tammy. C5.3 How are the amounts of substances in reactions calculated? This helps to show clearly any anomolous results and should help to convince students who are disappointed by a 1:1.25 ratio, for instance, that the correct formula really is MgO. The spectrum of light released during magnesium burning has a significant ultraviolet component. If magnesium makes a physical change then the color, shape, size, texture, and mass can change. It is best to start with a gentle blue flame, but you will need to use a roaring flame (with the air hole fully open) to get the reaction to go. Procedures Magnesium in air: Bassam Z. Shakhashiri, Chemical Demonstrations: A Handbook for Teachers of Chemistry, Volume 1. Replace the old foil with a new piece and try to repeat the experiment using a larger volume of solid fuel. The most significant hazard in this experiment is the hot apparatus. Burning Magnesium Science Experiment. Cut a piece of magnesium about 10–15 cm long. Keep a bowl of water nearby during the experiment. It is used in flares and fireworks because of its bright white light when it burns. Empirical formula of a compound gives the lowest whole number ratio of atoms of each element present in the compound. It is because of this extreme desire that magnesium is able to rip oxygen atoms straight off of other molecules.
