Science Coursework: Investigation to Identify the Formula of Hydrated Copper Sulphate and in doing so Find what x represents in the Formula CuSO4•xH2O Name: Matthew Dobson Partner: Jamie Barton? Date(s) Conducted: 23/04/05 - 06/05/05 Topic: Chemistry - Moles and Empirical Formulas Experiment: The Degree of Hydration of Copper (II) Sulfate, CuSO4 · xH2O Aim: I plan to investigate the formula of Hydrated Copper Sulphate and, more importantly, what x stands for in the formula (CuSO4.xH2O). This will tell me how many molecules of water surround each molecule of Copper Sulphate. To do this I plan to work out the amount of water a set mass of Hydrated Copper Sulphate loses when it becomes anhydrous. I will work this out by measuring the difference in mass between the two states. And thus ascertain the degree of hydration. I predict that because it is hydrated copper sulphate and it is blue that it will contain water of crystallization...
