According to Henry's law, what is the relationship between the solubility of an ideal gas and its partial pressure?
- The solubility of an ideal gas is inversely proportional to its partial pressure
- The solubility of an ideal gas is directly proportional to its partial pressure (correct)
- The solubility of an ideal gas is proportional to the square of its partial pressure
- The solubility of an ideal gas is independent of its partial pressure
