Question #fe5b8

Answer 1

Nothing will precipitate.

Explanation:

I assume that you are being asked to interpret a solubility graph something like this.

From the graph, it appears that the solubility of `"KNO"_3` is 40 g/100 mL of water.

Thus, if you start with a solution having 40 g of `"KNO"_3` in 100 mL of water at 100 °C and cool it to 25 °C, it will still hold 40 g of dissolved `"KNO"_3`.

The solution will be saturated, but no `"KNO"_3` will precipitate.
