Reaction of metals with oxygen Look at how magnesium reacts with oxygen: /**/ The use of a gas jar full of oxygen can be used to combust other metals. The balloon will expand to the same The experiment procedure was divided into two related investigations involving equal lengths of Magnesium ribbons and equal amounts of powdered Magnesium metal. Wrap the magnesium pieces immediately in an aluminum foil to prevent them from being re-oxidized. “h Cut magnesium into 3 pieces of 2, 3 and 4 cm “h Pour 30 cm 3 of 2 molar hydrochloric acid into a beaker. Half-fill a medium-sized test tube with 2 M hydrochloric acid. It can also be described as an oxidation-reduction reaction. One strip of magnesium is placed in a test tube containing 5 mL of water, and the other strip is placed in a test tube containing 5 mL of hydrochloric acid, HCl. This is because the hydrogen ions (H+) from the acid I have a large binding surface on magnesium metal but later, the surface area diminishes due to other factors in the reaction. VAT Registration No: 842417633. This will reduce reaction errors related to impurities. Repeat step 16 with 2M, 1.5M, 1M, and 0.5M HCL and clearly label your results. Reaction of Magnesium with Hydrochloric Acid OUTCOMES After completing this experiment, the student should be able to: develop a procedure for generating and measuring a gas in a reaction. When solid Mg reacts with HCl (hydrochloric acid), magnesium chloride (MgCl 2), … Place the test tube in a test-tube rack and add several magnesium turnings. Observations: Reactants: Products: Chemical Equation: 9. Determination of end of reaction was sometimes uncertain. Add 5 drops of potassium iodide solution. Remember to watch carefully and take detailed notes. These include the presence or absence of catalyst, temperature, concentration, and surface area of reactants. Temperature can have many chemical reactions on experiments or natural substances. Q. Hi, I was wondering if you could help me with my chemistry experiment, I have conducted an experiment in which I react magnesium ribbon with hydrochloric acid. New York: Oxford University Press. Metals that react with oxygen produce oxides as their products.
