3Question 3.
What is Henry's Law?
- A law about solids
- A law about gases solubility in liquids
- A law about boiling points
Show hintHide hint
Focus on which phase of matter is involved.
4Question 4.
Is a higher pressure on a gas always associated with higher solubility according to Henry's Law?
- True
- False
Show hintHide hint
Consider the relationship between pressure and solubility.
Question 5.
If the Henry's Law constant for oxygen in water at 25°C is 0.0031 mol/L·atm, what would be the mole fraction of oxygen in the water if the partial pressure is 0.21 atm?
Show hintHide hint
Make sure to apply the formula carefully.
Question 6.
A solution has a Henry's Law constant of 0.0344 mol/(L·atm) at 20°C. If the partial pressure is increased from 0.5 atm to 2.0 atm, calculate how much the mole fraction of the gas will change.
Show hintHide hint
Analyze the change based on the proportions given in Henry's Law.
