2.2. Calculating the Partition Constant

Try these first

1. 1.

   What are the three classifications of soil moisture?

   Hint

   Think about how moisture affects chemical binding.

2. 2.

   What characteristic defines 'wet' soil?

   Hint

   This distinction affects chemical binding.

3. 3.

   What type of soil is considered wet?

   • All mineral surfaces are uncovered
   • Full monolayer coverage of water
   • Partial coverage by water

   Hint

   Think about how the moisture is present.

4. 4.

   True or False: The partition constant K_A is higher in wet soils compared to dry soils.

   • True
   • False

   Hint

   Recall the relationship between moisture and K_A.

5. 5.

   Given a scenario where the moisture content of soil decreases from wet to dry, determine the implications on K_A and the environment.

   Hint

   Consider the storage and movement of compounds in the soil.

6. 6.

   Design a study to evaluate the impact of temperature changes on the partition constant in saturated versus unsaturated conditions.

   Hint

   Control the variables strictly.
