A solution is saturated in both nitrogen gas (N₂)and sodium iodide (NaI)at 50°C.When the solution is cooled to 25°C,which of the following is most likely to occur? A)Some nitrogen gas bubbles out of solution. B)Some sodium iodide will precipitate out of solution. C)Both A and B will happen. D)Nothing will happen. E)not enough information

Question

Quizplus · Accepted Answer

Sodium iodide has a solubility that decreases with decreasing temperature. Therefore, when the solution is cooled, some of the sodium iodide will precipitate out of solution. Nitrogen gas does not have a significant change in solubility with temperature, so option A is not correct. Option C is incorrect because only B is likely to happen. Option D is also incorrect because a change in temperature will cause a change in the solubility of one of the components in the solution. Option E is incorrect because there is enough information provided about the solubilities.
