Challenge Problems
Push your limits with advanced challenges
Given 150 kg of a chemical with a partitioning constant of K = 10, if mixed with 500 kg of water with a solubility of 1 mg/L, how would you assess the mass balance if the remaining mass in solid compounds is known to be 40 kg?
💡 Hint: Be sure to account for all phases.
If in a remediation scenario 80 kg of chemical X is found in water, 50 kg in solids, and you know that 20 kg is left undissolved, verify if calculations are balanced and what can be deduced.
💡 Hint: What does the left-over undissolved mass tell you?
