The Hydrates Lab

Before I begin to talk about this experiment may I include that this crystal lab blew my mind! (CuSO4 5H2O) We got blue crystals that weighed 5 grams and put them in a test tube over a flame to heat them up. When they were over the burner they began to turn white because the water was evaporating from the crystals. After they were fully white we weighted them in a cup at 1.73, this means that 3.2 grams of water evaporated. We got distilled water and poured it in the white crystlas and BOOM they turned back to the same exaclty blue color they started with!!
