Separation of a Mixture: Percent Composition—ChemTopic™ Lab Activity

firewatch

Most of the substances we come in contact with every day are mixtures. With the Separation of a Mixture: Percent Composition—ChemTopic™ Lab Activity, study the physical properties of salt, sand and iron. Use this information to design and carry out a procedure to separate a mixture of these substances, then calculate the mass percent composition of the mixture from the recovered components.

Concepts

  • Mixture vs. Pure Substance
  • Physical Properties
  • Percent Yield
  • Physical Changes
  • Mass Percent Composition
