Determination of the Water of Hydration in a Compound Purpose: This lab will help up practice the technique of weighing and teach us how to take a crucible and lid to constant weigh while calculating the percent of water of hydration and number of waters of hydration in an unknown compound from experimental data. Introduction: Water is an integral part of the crystal structure of many compounds. Water is held by strong coordinate covalent bonds in a definite proportion. The water in this form is referred to as water of hydration. Generally it can be driven out of the crystal structure by heating to high temperatures. What is left is called anhydrous salt. In this experiment you will observe the behavior of one hydrate and calculate the percent of water hydration for another. Procedure: Place a porcelain crucible and lid on a clay triangle supported by an iron ring on a iron stand. Place the crucible lid at an angle on the crucible so that it is not completely covered. Be careful not to drop the lid. Using a Bunsen burner, heat the crucible and lid
