This Determination of the Percent Hydration and the Simplest Formula of a Hydrate lab resource also includes:
- Lab & Experiment
- Worksheet
- Join to access all included materials
Does the crystal structure of a hydrated solid determine the proportion of water absorbed, or does the application of heat change the absorption? Scholars experiment with both variables to determine the answer. They add their collected data to a table and analyze the results with the provided questions.

Instructional Ideas
- Offer multiple types of hydrated solids to test, but ensure each student tests the same solid three times for accuracy
Classroom Considerations
- Relies on prior knowledge of the Law of Definite Proportions, salts, and measuring mass
- Use caution waving around the Bunsen burner and follow all safety precautions throughout the experiment
Pros
- Includes solving for experimental hydration, theoretical hydration, and percent error
- Provides an alternate method for completing the experiment without a Bunsen burner
Cons
- None
