Question and answer
Give comments on the result of experiment on determination of percent composition in hydrate compounds of copper(II) sulfate-5-hydrate.Discuss from the accuracy aspect of the results compared to the
theory.
Many ionic compounds, when crystallized from a water solution, take up a definite proportion of water as a part of their structure. The compound containing this water is known as a hydrate and the water is known as the water of hydration. [ If the hydrate is strongly heated, this water of hydration can be “driven off” as a vapor. The solid remaining is known as the anhydrous salt. Mass of
water = Mass of hydrate – Mass of anhydrous salt or (Mass of water = Mass of compound before heating – Mass of compound after last heating) The percentage of water in the hydrate can easily be calculated using the formula: % Water = Mass of water x 100 Mass of hydrate Formulas of Hydrates: Hydrates can contain varying amounts of water molecules in their structures. Some ionic compounds may have one, two, three, or more molecules of water associated with them. A common hydrate involves copper sulfate. There are five molecules of water associated with the compound copper sulfate. The formula for this hydrate is CuSO4 ·5H2O. The name given to CuSO4 ·5H2O is copper (II) sulfate pentahydrate. ]
