Challenge Problems
Push your limits with advanced challenges
Calculate the mass balance of a scenario where 200 kg of a contaminant is introduced in a body of water. Given the solubility of the contaminant is 50 mg/L and its partitioning constant with air is 0.5. How much will remain undissolved if the mass of water in the system is 1000 L?
💡 Hint: Calculate the maximum based on given volume and solubility first.
In a simulated spill, a chemical spills and partitions between air and water. If the partitioning constant is 10 (favoring water), and the initial concentration in water is estimated to be 300 mg/L, what might you predict about the air phase concentration?
💡 Hint: Refer to the definition of partitioning for the estimate.
