3.3. Initial and Equilibrium Mass of A

Try these first

1. 1.

   Define partition constant in your own words.

   Hint

   Consider how substances distribute in a system.

2. 2.

   What is moisture content?

   Hint

   Think about how we express it, like a fraction!

3. 3.

   What does K_oc measure?

   • Solubility of a chemical
   • Partitioning between solid and liquid
   • Viscosity of water

   Hint

   Think about how chemicals behave in different environments.

4. 4.

   True or False: Moisture content can only be defined on a dry solid basis.

   • True
   • False

   Hint

   Consider the definitions we've discussed.

5. 5.

   Design a simple experimental setup to measure the partitioning of a contaminant A. Outline steps including measurements for K_oc.

   Hint

   Think about how you will separate the phases after mixing.

6. 6.

   Analyze how changing moisture content in a solid affects the distribution of a contaminant in a scenario where the mass of solids is fixed.

   Hint

   Estimate how the added water volume would shift the overall balance.
