Question

helen needs to make a supersaturated solution of saltwater. which describes the best way to make the solution? increase the temperature of the solution and add more salt decrease the temperature of the solution and add less salt decrease the pressure and add more salt increase the pressure and add less salt

Explanation:

The solubility of salt in water generally increases with temperature. To make a supersaturated solution, we increase the temperature to dissolve more salt than the normal solubility allows at a lower - temperature, and then slowly cool it down while keeping the extra salt dissolved. Pressure has little effect on the solubility of solids in liquids. So increasing the temperature of the solution and adding more salt is the best way.

Answer:

increase the temperature of the solution and add more salt
