    Preparation of an Ionic Compound from Aluminum Metal October 6‚ 2010 The purpose of this laboratory project was threefold‚ in that it presented three main objectives. The first objective was to prepare the ionic compound alum from aluminum powder. The alum was produced from the reduction-oxidation reaction of aluminum with potassium hydroxide and sulfuric acid in water. The second objective was to then analyze the alum product for water crystallization; that is‚ to determine the value of x in

    Experimental Prep and Optimum wavelength Selection An ionic Iron solution with a known concentration of 4.047x10-3 M was obtained. A 250-mL sample of a 10-fold dilution of this ionic iron solution and 5 drops of concentrated HNO3 was made. This solution served as the source of ionic Iron for the remainder of the lab and was labeled “stock ionic Iron solution.” Next‚ a 50-mL aqueous ionic Iron and FerroZine® complex solution was prepared by adding 5.00mL stock ionic Iron‚ 3-mL of acetic acid buffer‚ 2-mL of 5%
