Q: discussion determination of percent composition in hydrate compounds
A: 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 the hydrate is heated. The remaining solid is known as the anhydrous salt. [ The general reaction for heating a hydrate is: Hydrate Anhydrous salt + water The ? sign means that heat is applied. The
percent of water in a hydrate can be found experimentally by accurately determining the mass of the hydrate and the mass of the anhydrous salt. The difference in mass is due to the water lost by the hydrate. The percent of water in the original hydrate can be calculated easily: % H2O = Mass of water x 100 Mass of hydrate In this experiment, a hydrate of copper (II) sulfate (CuSO4 · 5H2O) will be studied. The change from copper (II) sulfate pentahydrate to anhydrous copper (II) sulfate is accompanied by a change in color. CuSO4 · 5H2O CuSO4 + 5H2O Blue white This investigation should aid in the understanding of the composition of hydrates, simple decomposition reactions, and the Law of Definite Composition. ]
