Separating a Mixture by Filtration: Physical and Chemical Changes—ChemTopic™ Lab Activity

firewatch

Most of the matter around us consists of mixtures, physical blends of variable composition, of many substances that retain their distinctive chemical identities and unique physical properties. With the Separating a Mixture by Filtration: Physical and Chemical Changes—ChemTopic™ Lab Activity, separate a mixture of charcoal and salicylic acid, and determine the percent composition of each component in the mixture.

Concepts

  • Mixture vs. Pure Substance
  • Physical and Chemical Changes
  • Homogeneous vs. Heterogeneous
  • Filtration
