4.1. Aqueous Solubility

Try these first

1. 1.

   Define aqueous solubility.

   Hint

   Consider how substances interact with water.

2. 2.

   What does Rho A2 represent?

   Hint

   Recall the notation discussed for air and solid.

3. 3.

   What does Rho A1 represent?

   • Concentration of A in air
   • Concentration of A in water
   • Concentration of A in solid

   Hint

   Recall the specific index assigned to air concentration.

4. 4.

   True or False: Aqueous solubility is not important in environmental chemistry.

   • True
   • False

   Hint

   Think about why we need to understand how chemicals behave in water.

5. 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.

   Hint

   Use the definition of partition constant.

6. 6.

   Design an experiment to determine how aqueous solubility affects the spread of a contaminant in groundwater.

   Hint

   Consider factors like soil texture and organic content.
