Question

29.The solubility of oxygen gas in water is increased by which of the procedures shown below?Select one:a. Decreasing the temperature of the solution.b. Decreasing the pressure on the solution.c. Increasing the temperature of the solution.d. Stirring the solution.

Answer 1

According to Henry's law, which is a law that explains the solubility of gas in liquid, the increase of pressure will cause an increase of the solubility of a gas, but we also can increase the solubility with a decrease of temperature, which will cause the decrease of kinetic energy of the particles, therefore the best answer will be letter A
