Aim: Magnesium with Hydrochloric Acid In this piece of coursework I will investigate to see if concentration affects the rate of reaction between Magnesium (Mg) and Hydrochloric acid (HCl). The rate of reactions using different concentrations of acid will allow me to do this. The rate of reaction involves how long it takes for the reactants to turn into products and so in this investigation we are looking at the amount of Hydrogen gas produced at different concentrations to see if concentration does affect the rate of reaction between Hydrochloric acid and Magnesium. In groups we had to carry out the reaction between the two elements to see how much Hydrogen gas was collected. Purpose of investigation: Picture 3 The purpose of this investigation was to see if concentration affects the rate of reaction between Magnesium and Hydrochloric acid. Magnesium is one of the key reactants in the experiment. Magnesium is a chemical element found in the periodic table with the chemical abbreviation of ‘Mg’.It is a soft, light, silver/white metal and has an atomic number of 12 and an atomic mass of 24 and is the eighth most abundant element on the earth [1]. It is an alkaline earth metal and consists of 12 protons, 12 neutrons and 12 electrons. However the number of neutrons differs as there are different isotopes of Magnesium (Mg, solid). So in the first electron shell there will be 2 electrons present, however in the second electron shell there will be 8 electrons present and in the third electron shell there will be 2 electrons present, this can be written as 2,8,2. It appears as a silvery- white, hard element that is found in ribbon or powder form and burns a brilliant white flame. It’s highly flammable and very reactive, if the flame is looked at by a naked eye when burnt it can cause much damage. Magnesium is a solid meaning its atoms are packed more tightly
