Rates of reply GCSE COURSEWORK CHEMISTRY 2004 AIM In the sample we use hydrochloric sour which reacts with the atomic number 12 to mold milligram chloride. The hydrogen ions give hydrochloric acid its acidic properties, so that each(prenominal) solutions of hydrogen chloride and water have a sour line; 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, attribute Mg, silvery white metallic element that is relatively unreactive. In group 2 of the periodic table, milligram is one of the basic earth metals. The atomic number of magnesium is 12. The rate of a chemical reaction is a measure of how fast the response takes place. It is important to remember that a rapid reaction is cognize in a short period of clock time. An cause of a fast reaction is an explosion, and an example of a mute reaction is rusting. PLAN *Equations: M g+2HCl MgCl +H Mg+2H Mg+H The magnesium give 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 argon magnesium chloride and hydrogen gas. For my experiment the results will be measurable with a stop clock and the length of time the magnesium takes to dissolve will be measured. The results will be int erpreted down in a table, and then a graph ! will be drawn from the information. The submersion of hydrochloric acid is cypher by moles and I will vary the concentration from 0.5M- 3.0M. each time, a 1cm strip of standard width magnesium laurel wreath will be used. Each time...
