Unformatted text preview: Experiment: For this particular experiment, “Is It Economical to Recycle Aluminum?”, the process endures for two weeks in three particular stages. To start off, a 25ml water-filled beaker is used to combine with 8.0g of KOH. After creating the mixture, 2.0g of Al is dissolved into the beaker piece by piece to avoid the reaction from flooding out. After the process of dissolving the Aluminum foil into the mixture, the filtration system is to be setup by using a rubber stopper, filter paper, Buchner Funnel, and a hose that connects to running water. Pouring the mixture into the filtration system, the substance should be separated from the waste that will be left in the flask. Afterwards, mixing sulfuring acid into the flask to create a reaction. From this point on, 4.5mL of 9M sulfuric will be added to precipitate the aluminum hydroxide. Adding 13mL of the 9M H 2 SO 4 , which dissolves AlOH produced during the past reaction state. Then place in a cool place for crystallization. After formation, filtering out the liquid and a pipette to scrape out the place for crystallization....
