5.1. Partition Constants Between Water and Solid

Try these first

1. 1.

   What is a partition constant?

   Hint

   Think of it as a balance between two different states.

2. 2.

   What does Rho A2 represent?

   Hint

   It's part of a symbol system for representing concentrations.

3. 3.

   What does the partition constant K represent?

   • The ratio of chemical concentration in two phases
   • A measure of soil quality
   • The speed of chemical reactions

   Hint

   Think about what the constant describes in terms of different media.

4. 4.

   True or False: A chemical's partition constant can vary based on the type of soil present.

   • True
   • False

   Hint

   Consider how different soils interact with chemicals differently.

5. 5.

   Given a soil type has a KA32 partition constant of 3, what does this indicate about its retention of an organic pollutant? How might this impact environmental remediation efforts?

   Hint

   Consider how contaminants behave in different environments.

6. 6.

   If you have two different soils with identical partition constants, but one has a significantly higher organic content, how would you expect their behavior in environmental contexts to differ concerning organic pollutants?

   Hint

   Think about how organic matter interacts with organic pollutants.
