an aqueous solution is saturated in both oxygen gas and potassium iodide at 80 °c. determine what happens when the solution is cooled to room temperature. oxygen gas bubbles out of the solution. potassium iodide precipitates out of the solution. oxygen gas bubbles out of the solution and potassium iodide precipitates out of the solution. nothing happens. all of the oxygen gas and potassium iodide remain dissolved in solution

Answer

Brief Explanations:

The solubility of gases in water increases with decreasing temperature, so oxygen will not bubble out. The solubility of potassium iodide in water also generally increases with increasing temperature, but when cooling from 80°C to room - temperature, the solubility change is not large enough to cause precipitation for a saturated solution at 80°C. So both oxygen and potassium iodide remain dissolved.

Answer:

Nothing happens. All of the oxygen gas and potassium iodide remain dissolved in solution.
