What does Henry's Law state about gas in solution?

Henry's Law states that the amount of gas that can be dissolved in a liquid at a constant temperature is directly proportional to the partial pressure of that gas above the liquid. This means that as the pressure of the gas increases, more of it will dissolve in the liquid until a saturation point is reached. This principle is crucial in various applications, such as determining how carbon dioxide dissolves in beverages under pressure.

The relationship established by Henry's Law is fundamental to understanding how gases behave in liquid solutions, particularly in fields such as chemistry, environmental science, and medicine. Therefore, the direct proportionality between gas pressure and solubility described in this context aligns seamlessly with the principles of gas dynamics and solution chemistry, affirming the accuracy of the selected response.
