Question 13 • AA-F26 Physical Science

Helen needs to make a supersaturated solution of saltwater. Which describes the best way to make the solution?

Answer
A
increase the temperature of the solution and add more salt
B
decrease the temperature of the solution and add less salt
C
decrease the pressure and add more salt
D
increase the pressure and add less salt

Explanation

A supersaturated solution contains more dissolved solute than it normally can hold at a given temperature. Heating the water increases how much salt can dissolve, so Helen should increase the temperature and add more salt. Cooling it afterward can leave the extra salt dissolved temporarily, creating a supersaturated solution.
