separating Mixtures
  • Chemical properties may be used to separate some mixtures
  • Mixtures can be separated by physical means
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

  • 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
