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 1.5M potassium hydroxide and 9M sulfuric acid were added, why was this information not precise?

    I synthesized Common Alum in my lab. KAl(SO4)212H2O(s) We then had to find the water content based on the initial mass of the Common Alum subtracted from the anhydrous mass after heating. I had 1g of the Common Alum and after heating it, I had 0.57g and I was able to find the percent of water content: 43%. 1g - 0.57 = 0.43g 0.43g / 1g = 0.43 x 100 = 43% Now I have to calculate the percentage error...
