Brandon Comiskey-Lucero ChemL121 Sec 8 27 September 2018 Isaac and Amanda Synthesis of Common Aluminum Abstract: In this experiment we experimented with the elemental properties of aluminum and to explore its theoretical yield of the reactions associated with aluminum. Introduction: The purpose for the second part of the experiment was to confirm the chemical and physical properties of the substance that was created in the previous lab. To test it we will have to preform one qualitative test and two quantitative tests. Experimental Data: Aluminum Hydroxide vs Aluminum Ion- Add 3 mL of 0.1M Al(NO 3 ) 3 the main source of Al 3+ to a large test tube. Add 6M NaOH Observations: The Al(NO 3 ) 3 turned more solid with egg drop soup looking pieces in it, but once it is shaken well, the solution is clear. Synthesis of Common Alum Obtain aluminum and weigh it. Place Aluminum in a beaker and add menthol red.
Obtain 6M H 2 SO 4 and heat solution Wait for it to cool and then filter crystal/dry Submit sample in vial.
