DETERMINATION OF WATER OF CRYSTALLIZATION

- Aim: To determine the formula of the hydrate of copper (II) sulfate.
- Hypothesis:
Hydrates are ionic compounds that have a definite amount of water as part of their structure. The water is chemically combined with the salt in a definite ratio. Ratios vary in different hydrates but are specific for any given hydrate.
In this experiment, the hydrate of copper sulfate has the formula CuSO4.xH20. When it is heated, the water is released as vapor and we can describe the reaction as below:
Hydrate Anhydrous salt + Salt
CuSO4.xH20 CuSO4 + xH20
