4.1. Comparison with Aqueous Solubility

Try these first

1. 1.

   Define the term 'Partition Constant'.

   Hint

   Think about how chemicals behave in different states.

2. 2.

   What does 'Aqueous Solubility' refer to?

   Hint

   Consider how much of a chemical can saturate water.

3. 3.

   What is the role of the partition constant (K)?

   • Describes solubility
   • Indicates chemical distribution
   • Measures toxicity

   Hint

   Focus on the definition.

4. 4.

   True or False: Aqueous solubility can be exceeded in a sample of water.

   • True
   • False

   Hint

   Recall what solubility means.

5. 5.

   You have a soil-water system with 200 kg of a contaminant and Koc of 5. Calculate the distribution if aqueous solubility is limited to 20 mg/L.

   Hint

   Use the partitioning formula and given values to set the equilibria.

6. 6.

   Design a remediation strategy for a site with complex contaminants. How does the knowledge of Koc, solubility, and moisture content influence your approach?

   Hint

   Consider both phases and the behaviors of different chemical types.
