Unformatted text preview: Kris Kelly Activity Series Lab CHEM 121L 10/30/07 Introduction/Background: In this experiment, six various metals will react with seven different metal ion solutions. These will all be electron-transfer reactions, meaning that the metal will give away electrons to the metal ion in the solution. For example: Ca + CuSO CaSO + Cu Calcium will have given away two electrons to the copper in solution, thus making copper have a neutral charge after it had a +2 charge in solution with the sulfate. A number of these reactions are exothermic, which is a reaction that gives off heat as it occurs. Key Data: Metal Reaction with HCl Observation Equations Ca Yes, quickly Violent bubbling to evolve a gas Ca + HCl CaCl + H Ca + 2H Ca + H Cu No No visible reaction Cu + HCl no reaction Mg Yes, quickly Violent bubbling to evolve a gas Magnesium fully dissolved Mg + HCl MgCl + H Mg + 2H MgCl + H Fe Yes, slowly Slow evolution of a gas Fe + HCl FeCl + H Fe + 2H Fe + H Sn No No visible...
