Classic AP Requirement #2—Determination of the Percentage of Water in a Hydrate

Students analyze aluminum potassium sulfate (alum) using three techniques to determine its exact composition. The following properties are determined: melting point, the moles of hydrated water per mole of alum and the percent sulfate in the compound. Each of these determinations is compared to the literature or calculated values for alum. Students will gain valuable experience with the analytical process and techniques of gravimetric determinations.

Complete for 24 students working in pairs.
