5. Partitioning Between Phases

Try these first

1. 1.

   Define mass concentration.

   Hint

   Think about the basic formula of mass over volume.

2. 2.

   What does the symbol ρA represent?

   Hint

   Remember what ρ symbolizes in the context of concentration.

3. 3.

   What does mass concentration refer to?

   • Mass of a substance per unit volume
   • Mass of a substance per unit area
   • Volume of substance per unit mass

   Hint

   Think about how we measure substances in solutions.

4. 4.

   True or False: Partition constants are equal in different locations if the properties do not change.

   • True
   • False

   Hint

   Consider stability across locations.

5. 5.

   You have a contamination scenario with two different soils. Predict how each will hold the same chemical based on their partition constants.

   Hint

   Consider how organic content influences retention ability.

6. 6.

   Given two chemicals with different partition constants, explain how environmental conditions could influence their movement through soil into groundwater.

   Hint

   Focus on the interplay between environmental conditions and chemical properties.
