Magnesium reacts with dilute hydrochloric acid in a conical flask which is connected to an inverted measuring cylinder in a trough of water. The tube through the bung should be a short section of glass, and then a flexible rubber tube can be connected. When aqueous hydrochloric acid (HCl) is mixed with solid Magnesium carbonate (MgCO3), it will give carbon dioxide (CO2), magnesium chloride (MgCl2) and water as results. Burning magnesium is an exothermic reaction because when magnesium and oxygen particles collide to form new bonds, energy is released into the surroundings. Make sure all of the Mg is added to the hydrochloric acid solution. Draw tangents to the curves on these graphs and use the slope of the tangent as a measure of the rate of reaction. It takes place because magnesium is more reactive than hydrogen so it displaces it in the chloride compound. Graph 1: Rate-reaction trends of magnesium metal ribbon and powder with increasing concentration of HCl, Calculations Mg (s) + 2HCl (aq) MgCl 2 (aq) + H 2 (g) Students follow the rate of reaction between magnesium and the acid, by measuring the amount of gas produced at 10 second intervals. But this is no substitute for doing the experiment yourself (safely of course, while you wear safety specs to protect your mince pies, and a lab coat to protect your clothing), and closely observing the reaction. Reaction with oxidizers such as permanganates, chlorates, chlorites, and hypochlorites may produce chlorine or bromine gas. The color of eachsolution is red, indicating acidic solutions. Continue timing until no more gas appears to be given off. The formation of the hydroxide can be illustrated using universal indicator. I want to help you achieve the grades you (and I) know you are capable of; these grades are the stepping stone to your future. How hydrogen is produced from an acid and magnesium? When zinc reacts with hydrochloric acid it produces zinc chloride and hydrogen gas. The volume of hydrogen gas produced is measured over a few minutes, and the results are used to plot a graph. Chemicals and Reagents (b) Magnesium metal is treated with dilute hydrochloric acid. These metals react with with dilute sulfuric acid just as they did with dilute hydrochloric acid; the reaction between magnesium and dilute sulfuric is familiar to many beginning chemists.
