1.1. Physical and Chemical properties of interest

Try these first

1. 1.

   What is aqueous solubility?

   Hint

   Think about what happens when you add too much salt to water.

2. 2.

   How is vapor pressure related to a chemical's volatility?

   Hint

   Consider which liquids evaporate quickly.

3. 3.

   What does aqueous solubility indicate?

   • How much solute can dissolve in water
   • The weight of the solute
   • The temperature of the solute

   Hint

   Think about what it means to dissolve something.

4. 4.

   True or False? A higher vapor pressure means a chemical is less volatile.

   • True
   • False

   Hint

   Consider which type of substances evaporate more readily.

5. 5.

   If the aqueous solubility of chemical X at 25°C is 50 mg/L and the vapor pressure is 20 mmHg, how would you describe its behavior in an aquatic environment?

   Hint

   Consider what happens to substances in water compared to those in the air.

6. 6.

   Given a scenario with two chemicals, A and B, where A has a higher aqueous solubility but lower vapor pressure than B, which one will likely accumulate more in the aquatic environment?

   Hint

   Think about the balance of being dissolved vs. evaporating.
