Part 8: Side Reactions 8. Chemical reactions are rarely straight forward, and "side reactions" can be occurring simultaneously. In the video, yoki saw the production of a gas and the evolution of heat. You may have noticed the instructor in the video added hydrochloric acid before adding aluminum. Acids are introduced in section 4.3 of the text. a. After reviewing section 4.3, write the reaction of aluminum metal with hydrochloric acid. Include phase labels on all reactants and products. b. Does this "side reaction" explain the formation of bubbles during the chemical reaction? Explain. c. Type out the complete ionic equation and the net ionic equation for this reaction. d. Explain how you arrived at your answer in a narrative (1-3 sentences), including why you canceled any lons as spectators. Include phase labels on each species. Part 9: Reporting Results....Like a Chemist (Results and Discussion) 9. Provide a 2-4 paragraph summary that includes: a. What the experiment did and what you observed. Identify the type of reaction for the copper(II) chloride dihydrate and aluminum reaction, as well as the aluminum and hydrochloric reaction. Explain why they fall into these categories. b. Describe the results and calculations that led to the determination of the limiting and excess reactants. This means, to recap, in words, how you calculated the limiting and excess reactants, and provide the numerical results as evidence. c. Calculated values should match experimental evidence. In this experiment, solid copper was isolated, AND a solution remained in the flask. Discuss (3-5 sentences) the calculated results of the limiting/excess reactant and how this would predict the color of the final solution. d. Identify the percent yield value. Explain what factors could cause this yield to be different than 100 % . Would "side reactions" affect the yield? If so, how? fantha Cahadula and Causea Bubelns la Cullahu Madulo for dua daton and mending information 3
