AP Chemistry Lab 2: Analysis of Alum Lab Objective: In this lab we will analyze alum by two techniques in order to verify its identity. The melting point and the mole ratio of hydrated water to anhydrous aluminum potassium sulfate will be determined. Lab Procedure: 1. Use a mortar and pestle to crush alum. 2. Pack the alum in capillary tube‚ and then fasten it to the thermometer. 3. Fasten the thermometer to the ring stand. 4. Immerse the bottom of the

three separate procedures in which Aluminum Potassium Sulfate(Alum) will be melted‚ massed out and mixed with Barium Nitrate‚ along with distilled Water. Procedure one we completed two trials of melting two separate 0.01g of Alum and making a comparison to the literature temperature of 92.5‚ to do this we attached an Alum filled capillary tube to a thermometer and inside a beaker placed over a Bunsen burner. Procedure two consisted of placing 2.00 grams of Alum into a crucible and heating it over
