Formula of a hydrate lab
In lab this week the first lab we performed was the formula of a hydrate lab. The first step in this lab was to measure the mass of the test tube in which we would be conducting the lab. Next we placed about 2 cm of hydrated crystal in the bottom of the test tube. Next we measured the new mass of the test tube with the crystals in it. We then placed the test tube on the ring stand and heated the test tube for a few minutes until the color of the substance changed from blue to white. We remeasured the mass of the test tube, and then heated the test tube again to try to drive off any left over liquid.

That was a fun lab, and it was pretty easy to do. All you really had to do was wait for the blue color to vanish from the test tube. Ours was pretty good after the first weighing.
