Chemical Reactions and Properties

Chapter 2, Lesson 4

By : Alex Wallace


Separating mixtures
separating Mixtures

  • Chemical properties may be used to separate some mixtures

  • Mixtures can be separated by physical means


Separating metals from ores
Separating metals from ores

  • Ores are rocks that include metals combined with other substances

  • People may use chemical properties to separate metals from their ores, like heating iron with solid carbon


Identifying substances
Identifying Substances

  • Scientists use physical properties to identify substances

  • Chemical properties are used to identify acids or bases

  • Weaker or stronger acids and bases leave different colors

  • Universal indicator paper and flame tests are used to identify acids and bases
