IntroductionAluminum is a common metal you find being used in everyday life such as soda cans Due to its constant use people have discovered fast and efficient ways to recycle aluminum cans for re use Placing the aluminum in a series of solutions and filtering processes aluminum can be recycled for future use The process to recycle is 92 more energy efficient than the actual production of aluminum cansMaterials and MethodsThe mass of the 250 mL beaker used in this experiment weighed 11452 grams The mass of the aluminum strips weighed 99 grams for a combined weight of 11551 grams of the aluminum strips inside the 250 mL beaker 50 mL of 14 M Potassium Hydroxide KOH was placed in the beaker with the aluminum strips and left on a hot plate heated at 70 degrees Celsius to cook The solution began to bubble and get foggy while it was being stirred every few minutes with a stirring rod every few minutes Every few minutes the solution would become grayer in color until the solution itself turned into a really dark gray This meant the aluminum strips had melted completely and the dark solution was filtered into a suction flask with a Buchner funnel The filtered solution was then placed into the 250 mL beaker that was cleaned with distilled water The beaker holding the solution was placed on a hot plate while 20 mL of 60 M sulfuric acid slowly The combined mixture would solidify and look white but would become clearer and clearer as it became liquefied after constant stirring and heating Once the mixture was absolutely cleared it would go through the filter aspiration one more time and then it was placed in an ice bath for alum crystals to form Once crystals formed the solution was filtered one last time to collect any crystals that were formed and then the crystals were cleaned with 50 ethanol Results and DiscussionsThe weight of
