The hydration number of CuSO4 and MgSO4 was found by heating solutions in a crucible. There was more hydration present in MgSO4 than in CuSO4. The variance is going to change because of different amounts of heating and outside factors. Our results came out very precise and accurate. Purpose: The purpose of this experiment is to make anhydrous out of the hydrated compounds, MgSO4 and CuSO4. The numbers found when the anhydrous was formed will then calculate the masses of the hydrate. A formula will then be calculated for the hydrate compound. A real life example of using a hydrate is with cement. When the contractors pour the cement they try to keep the cement hydrated as long as possible so the water doesn’t dissolve into the air (from being heated). When the water from the cement evaporates, it causes major cementing problems like cracking and shrinking. Procedure: Refer to Experiment 3 in Utecht, R.; Downey, T.; Miller, M; Hirko, R. Chem 112L – General Chemistry I Laboratory , Cache House, Inc: Eden Prairie, MN, 2007. Two trials were conducted instead of three.
