Question 1.
What is Henry's Law Constant?
Show hintHide hint
It's about the relationship between air and water concentrations.
Question 2.
Define aqueous solubility.
Show hintHide hint
Think about how much salt can dissolve in water.
3Question 3.
What is the main application of Henry's Law Constant?
- To determine temperature changes
- To predict the distribution of chemicals between phases
- To measure pressure
- None of the above
Show hintHide hint
Think about the balance between air and water concentrations.
4Question 4.
True or False: A higher Henry's Law constant indicates a substance is more soluble in water.
- True
- False
Show hintHide hint
Recall the relationship between solubility and concentration.
Question 5.
Assume you have a substance with a Henry's Law constant of 0.005. If you have 10 mg in a 1-liter water sample at equilibrium, what would be the concentration in the gas phase?
Show hintHide hint
Use the equilibrium formula relating air and water concentrations.
Question 6.
A lake has a concentration of a pollutant at 50 mg/L, and its Henry's Law constant is 0.001. Calculate the expected concentration of the pollutant in the air.
Show hintHide hint
Recall the formula and apply the given values carefully.
