A solution is saturated in both nitrogen gas N2 and sodium iodide NaI at 50 degree Celsius. When the solution is cooled to 25 degree Celsius, 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

b. some sodium iodide will precipitate out of solution

Explanation:

We know that for salts solubility decreases as the temperature of the solution decreases. So, NaI being a salt, its solubility will surely decrease when the temperature is cooled down to 25°C from 50°C.

Thus,the undissolved sodium iodide will precipitate out of the solution.

-be a crystalline solid

- be soluble in water

-conduct electricity

hope this : )

3 hours because it is a decent distance.
