Rates of reaction between magnesium ribbons and hydrochloric acid. GCSE coursework.

Rates of reply GCSE COURSEWORK CHEMISTRY 2004 AIM In the examine we use hydrochloric sour which reacts with the atomic number 12 to puddle milligram chloride. The henry ions give hydrochloric acid its acidic properties, so that each(prenominal) solutions of hydrogen chloride and water have a sour nidus; corrode active metals, forming metal chlorides and hydrogen; turn litmus red; neutralise alkalis; and react with salts of weak acids, forming chlorides and the weak acids. Magnesium, nominal Mg, silvery white metallic element that is relatively unreactive. In group 2 of the periodic table, milligram is one of the alkalescent earth metals. The atomic number of magnesium is 12. The rate of a chemical result is a measure of how fast the response takes place. It is important to remember that a rapid reaction is realize in a short period of clock time. An congressman of a fast reaction is an explosion, and an example of a wearisome reaction is rusting. PLAN *Equations: Mg+2HCl MgCl +H Mg+2H Mg+H The magnesium pull up stakes react with hydrochloric acid, because it is higher in the reactivity series that hydrogen. When the two chemicals react, a ejectment reaction will take place and the magnesium will displace the hydrogen in the hydrochloric acid forming magnesium chloride and hydrogen gas.

Therefore, the products of the reaction are magnesium chloride and hydrogen gas. For my experiment the results will be mensural with a stop clock and the length of time the magnesium takes to dissolve will be measured. Th e results will be interpreted down in a tabl! e, and then a interpret will be drawn from the information. The submersion of hydrochloric acid is mensurable by moles and I will vary the concentration from 0.5M- 3.0M. distributively time, a 1cm strip of standard width magnesium screw thread will be used.
