2.3. Henry's Constant and Solubility of Chemical A

Try these first

1. 1.

   Define Henry's Constant.

   Hint

   Think about gas solubility.

2. 2.

   What does solubility indicate?

   Hint

   It’s a limit on how much goes into the solution.

3. 3.

   What defines Henry's constant?

   • A measure of gas pressure
   • A measure of gas solubility
   • A measure of liquid volume

   Hint

   Think about gases dissolving.

4. 4.

   True or False: The solubility of Chemical A can change based on temperature.

   • True
   • False

   Hint

   Consider how temperature affects substances.

5. 5.

   If 200 kg of Chemical A is introduced into a system with 1,000 L of water and 1,000 kg of soil, and your solubility is 2 mg/L, how will you approach the mass balance?

   Hint

   Remember to check if the concentration exceeds solubility.

6. 6.

   Discuss the implications of having a high Koc (5) in assessing Chemical A's environmental risk.

   Hint

   Consider how soil interaction influences transport.
