Lesson Plan: Volatilization Gravimetry Chemistry
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to use volatilization gravimetry to calculate the quantity of analyte in a sample or determine the formula of a hydrated compound.
Objectives
Students will be able to
- define the volatilization method in gravimetric analysis,
- describe the experimental procedure involved in volatilization gravimetry,
- connect the loss of mass of a hydrated compound with the loss of water molecules from the compound,
- calculate the percentage of water of crystallization in a hydrated compound,
- calculate the stoichiometry of a hydrated crystal based on the hydrated and dehydrated masses of a sample.
Prerequisites
Students should already be familiar with
- formula or molar mass.
Exclusions
Students will not cover
- properties of hydrated crystals,
- deliquescent compounds,
- the crystal structure of hydrated crystals.
