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. Kit Includes: 2 x 100g Aluminum Potassium Sulfate 4 x 25g Barium Nitrate DOT Info: Small quantity exemption 173.4 THIS PACKAGE CONFORMS TO 49 CFR 173.4 for domestic highway or rail transport only
