How Hard Is Your Water? Microscale Titration—ChemTopic™ Lab Activity

firewatch

As water flows through rocks and soil, it picks up minerals from the Earth’s surface. Although many minerals are essential for life and desirable for health, high levels of calcium, magnesium and iron in “hard water” cause problems in homes and in industry. With the How Hard Is Your Water? Microscale Titration—ChemTopic™ Lab Activity, analyze water hardness levels of various water sources by microscale titration with EDTA.

Concepts

  • Water Hardness
  • EDTA Ttitration
  • Chelates and Complex Ions
  • Water Softening
