Gravimetric analysis lab high school chemistry

Gravimetric analysis is a fundamental technique in chemistry, providing a hands-on approach to quantitatively determining the amount of a substance in a sample by measuring its mass. This gravimetric analysis lab is designed to engage students in the principles and techniques of gravimetric analysis while reinforcing key concepts in stoichiometry, chemical reactions, and quantitative analysis.

Students will gain an understanding of precipitation reactions, analytical chemistry techniques, fundamental types of gravimetric analysis, applications of the gravimetric method and practice determining the percent composition of an original sample.

What is included in the gravimetric analysis lab?

• scaffolded notes on gravimetric analysis
• pre-lab questions
• scaffolded experiment outline
• post-lab questions and calculations
• gravimetric analysis practice questions

Calculation questions involve:

• knowledge of the solubility rules
• writing chemical equations
• calculating the moles of precipitate
• calculating the mass of an ion (e.g. mass of sulfate)
• determining the percent composition in a known mass of sample

This Gravimetric analysis experiment resource is suitable for students in grades 10 - 12 studying chemistry.
