What is a partitioning constant?
Think of it as a ratio of concentrations.
Define mass balance.
Remember the law of conservation of mass.
What does a partitioning constant indicate?
Consider how you measure amounts in different compartments.
True or False: Equilibrium ensures that the concentration of a chemical in another phase can exceed its solubility.
Recall how solubility sets limits.
In a controlled experiment, a researcher adds 120 kg of a chemical to a pool with a total volume of 1500 m³ of water. If its aqueous solubility is found to be 0.5 mg/L, determine how much of the chemical remains in pure form, assuming it partitions according to its solubility limit.
Start by calculating the maximum concentration allowed in water.
Given a scenario with 200 kg of a chemical. If 30% partitions into the water phase and 20% into the solid phase, how much is in the pure phase? Describe the implications of this distribution for environmental safety.
Review the partitioning balance to determine the remaining mass.
