This lab seeks to dehydrate a hydrated salt, determine what percentage of water is in the hydrate, and to find the ratio of the salt and water molecules. The lab takes a hydrated salt (a salt is an ionic compound other than water formed by the reaction of an acid and a base, and hydrated means that water is in the crystalline structure of the salt) and attempts to dehydrate it. To do this with copper (II) sulfate, one must heat the hydrated copper (II) sulfate until the water evaporated. This will be evident because the hydrated crystal in this case is blue, and when it is dehydrated (anhydrous) it is white. The lab asks to find the percent of water in the hydrate, so by finding the amount of water lost (the difference between the hydrated and anhydrous salt), one should be able to find that percent.
