3 cards from this section. Quick, good the night before a test.
Define mass concentration.
Think about how density is calculated.
What does a partition constant indicate?
Consider how chemicals behave in different environments.
What does mass concentration represent?
Consider the units of mass and volume.
True or False: A partition constant indicates the concentration of a chemical at equilibrium.
Remember the definition of equilibrium.
A pollutant with a partition constant of 10 between air and water is found in groundwater. If the concentration in air is 100 μg/m³, what is the equilibrium concentration in water?
Use the definition of partition constant.
You collect soil samples from two different areas: sandy soil and clayey soil. Explain how you would determine which area is more likely to lead to groundwater contamination from chemical leaching.
Think about the properties of the soil types and their effects on chemical movement!
