After mystery hydrate 1 was chosen to be the first sample to work with, the mass of the crucible was measured, then measured again with a small amount of the hydrate inside it. After making observations of the hydrate, the sample in the crucible was placed over a burner for a short amount of time. After enough physical changes had occurred to justify the claim that there was a change in the substance, the crucible was removed from above the burner and set down to cool. After cooling, the crucible was measured again to determine the difference in mass. During the second measurement, the mass was lower. This was due to the fact that when the crucible was over the burner, the high temperature caused any water in the substance to evaporate, and scorched and burned some of the solid substance as well. After making observations about the changes in the hydrate, the experiment was repeated with mystery hydrate 2.
