Recycling Al experiment Mass of Al : 0.49g Mass of KAl(SO4)2 12H2O synthesized: 2.86g 1. Assuming you started with pure aluminium scrap, calculate the theoretical mass of the precipitate, alum. Include a balanced net ionic equation for the formation of the product from Al3+. 2. Calculate your percent yield. 3. If you had a large number amount of impurities in the scrap aluminium, what would be the impact in the percent yield calculation? explain. 4. In this experiment volume of...
