Dissolved Oxygen Testing: Biochemical Oxygen Demand and Water Quality—ChemTopic™ Lab Activity

firewatch

The amount of dissolved oxygen in water is one of the most important indicators of water quality and environmental health. How do factors like temperature, dissolved salts and organic matter affect the level of dissolved oxygen? With the Dissolved Oxygen Testing: Biochemical Oxygen Demand and Water Quality—ChemTopic™ Lab Activity, investigate the effects of various environmental factors on the amount of dissolved oxygen in water by using the Winkler method.

Concepts

  • Dissolved Oxygen
  • Biological Oxygen Demand
  • Winkler Titration
  • Water Quality
