After a compound has been synthesized, analytical tests should be carried out to confirm that the correct compound has been produced. In this lab we will perform tests to confirm that the crystals formed are in fact potassium aluminum sulfate 12 hydrate by comparing the melting point to published results, finding the number of waters of hydration, and determining the percent of sulfate in the compound.
2 x 100g Aluminum Potassium Sulfate
