Pre-Lab Title: Hydrates Lab Purpose: This investigation should aid in the understanding of the composition of hydrates and simple decomposition reactions. The purpose is to determine the percent of water in a hydrate. Materials: 1. Evaporating dish 5. Iron Ring 8. Crucible tongs 2. Wire gauze 6. Microspatula 9. Bunsen burner 3. Laboratory balance 7. Safety glasses 10. Ring stand 4. Copper (II) sulfate hydrate Procedure: 1. Prepare the set up shown in figure. 2. Heat the dish with the hottest part of the flames for 3 minutes. 3. Leave the evaporation dish on the gauze and let it cool for 3 minutes.
