2 cards from this section. Quick, good the night before a test.
Define partition constant.
Think about how chemicals behave in liquids and solids.
What does moisture content represent?
It's often expressed as a fraction.
What does the partition constant indicate?
Think about where the chemical is more likely to remain.
True or False: Equilibrium implies dynamic concentrations.
Consider what equilibrium actually means.
Given 200 kg of a pollutant with a Koc of 5 (in L/kg) is added to a wetland system (V = 1000 m³), with 50% moisture content in soil (mass = 1500 kg), determine the concentration in water and solid phases at equilibrium.
Start by calculating the total mass from Koc and then distribute based on the given conditions.
Consider a case where a chemical has a solubility of 2 mg/L but you calculate—based on Koc and mass input—10 mg/L in water. What does this suggest about the contaminant segregation?
Relate your findings back to the basic principle of solubility and partitioning.
