Introduction: This lab was performed to provide a study of chemical recycling and provide experience in inorganic synthesis. Aluminum is the main material used in the production of beverage cans. However, it’s a very costly material to manufacture as it requires large amounts of chemical energy to be made. Therefore, they is constant research being conducted to make sure that aluminum will see its true potential, as the life of an aluminum can is about one hundred years. Alum or potassium sulfate is the byproduct of transformed scraped aluminum and is widely utilize in the dyeing of fabrics, and the manufacturing of pickles. It’s also used as a coagulant in water-purification and waste-water treatment plants. Alums are ionic compounds that “crystallize from solutions containing sulfate anions, a trivalent cation and a monovalent cation”. Purpose: The concept of this experiment was to provide an opportunity to gain valuable insight in the fundamental aspects of inorganic synthesis by coming to terms with some very important and useful skills. In the first part of the experiment, a better understanding of the reactivity of aluminum was grasped. Then in the second and third part, the proper dissolution methods of alum were clutched. Finally, the proper methods for
