Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

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?

💡 Hint: Use the definition of partition constant.

Challenge 2 Hard

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.

💡 Hint: Think about the properties of the soil types and their effects on chemical movement!
