4Question 4.
True or False: Aqueous solubility is not important in environmental chemistry.
- True
- False
Show hintHide hint
Think about why we need to understand how chemicals behave in water.
Question 5.
If the concentration of a chemical in water (Rho A2) is 0.5 mg/L and in air (Rho A1) is 0.02 mg/L, calculate the partition constant K_A21.
Show hintHide hint
Use the definition of partition constant.
Question 6.
Design an experiment to determine how aqueous solubility affects the spread of a contaminant in groundwater.
Show hintHide hint
Consider factors like soil texture and organic content.
