Percent Composition of a Hydrate Lab
The percent composition of a hydrate lab is a fundamental experiment in chemistry that demonstrates the concept of hydration and the determination of the empirical formula of a hydrate. It involves the quantitative analysis of a hydrate, a compound that contains water molecules bound to a salt in a specific ratio.
Lab Overview, Percent composition of a hydrate lab answer key
The purpose of this lab is to determine the percent composition of a hydrate by measuring the mass of water lost upon heating and the mass of the anhydrous salt remaining. The steps involved in conducting the lab include:
- Measuring the mass of a crucible and lid.
- Adding a weighed sample of the hydrate to the crucible.
- Heating the crucible and hydrate using a Bunsen burner until all the water has been driven off.
- Cooling the crucible and anhydrous salt and measuring the mass.
- Calculating the mass of water lost and the percent composition of the hydrate.
Materials and Equipment
The following materials and equipment are required for the lab:
- Hydrate sample
- Crucible and lid
- Bunsen burner
- Wire gauze
- Tongs
- Analytical balance
- Desiccator
