While dissolving a gas into a liquid at a constant temperature, the ratio of the concentration of the gas in the solution phase and in the gaseous phase is _______________?
Correct answer: D. Constant
- A. Infinity
- B. Unity
- C. Negative
- D. Constant
Explanation
At constant temperature, gas-liquid equilibrium follows Henry’s law, so the ratio of dissolved-gas concentration to gas-phase concentration remains constant. It is not necessarily unity because the two phases generally have different concentrations.
