The purpose of the lab is to identify the compound based on a constant composition by performing a serious of tests. The hydrate is solid crystals compound and appears to be dry: since an ionic compound (salt) is crystallized from an aqueous solution (water), by heating the hydrate the water is released from ionic structure; therefore it is possible to measure the weight of the ionic compound and calculate its ratio to the liquid in the hydrate. The goal of the lab is to establish the identity of a given hydrate (“wet salt”) by comparing the results with known hydrate percentages. Hydrates are ionic compounds (salts) that have a definite amount of water as part of their structure. This “water of hydration” is released as vapor when t...
