Challenge Problems
Push your limits with advanced challenges
You have a scenario where a chemical has a Koc of 30. If you introduce 150 kg of this chemical into a lake with 1,000,000 kg of water and 50,000 kg of wet solids, calculate the mass proportion in each phase at equilibrium.
💡 Hint: Remember to incorporate moisture content when working with wet solids.
Discuss and model the implications of introducing a substance that exceeds its solubility. How would this influence potential environmental remediation strategies?
💡 Hint: Think about why it’s essential to know the quantities of undissolved substances.
