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

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

Answer

Brief Explanations:

The solubility of salt in water increases with temperature. To make a supersaturated solution, we need to dissolve more solute (salt) than the normal saturation point. Increasing the temperature allows more salt to dissolve, and then adding more salt and slowly cooling it (while keeping the extra - dissolved salt from precipitating out immediately) can create a supersaturated solution. Pressure has little effect on the solubility of solids in liquids like salt in water.

Answer:

increase the temperature of the solution and add more salt
