Lesson Plan: Volatilization Gravimetry Chemistry • Third Year of Secondary School
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.
