Product Details

See the true colors of copper carbonate. The empirical formula of copper carbonate is not obvious but its parts can be investigated and related to the composition of the whole. Students measure the amount of gas generated and apply colorimetric analysis to determine the identity of an unknown copper carbonate. This hands-on experiment will help students learn the concepts of empirical formulas, standard dilution, percent composition, and colorimetric comparison. Includes reproducible student handouts, detailed background information, complete Teacher Notes with sample data and answers to questions and all chemicals needed to perform the lab. Complete for 30 students working in pairs.

Performance Expectations

MS-PS1-1. Develop models to describe the atomic composition of simple molecules and extended structures.
MS-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
MS-PS1-5. Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved.
HS-PS1-1. Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.
HS-PS1-2. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
HS-PS1-7. Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.
