Hydration of an Ionic salt
Objective: Determine how much water is integrated into a salt. We have been learning about Empirical formulas in class and this is an opportunity to use what we have been learning. Remember the empirical formula is the simplest ratio of atoms.
Procedural Summery:
We will be heating a hydrated salt in a crucible. Through weight differences we will be able to determine the mass of dehydrated salt and water. With these values we can easily determine the percent by mass of water and salt. After which we will also be determining the individual ratio between number of water molecules and number of salt units.
The salt we will be using is CuSO4 *nH20. The "n" represents the number of water molecules huddled around each Copper (II) sulfate crystal.
