Question
What is one way to change the volume without changing the concentration?
Describe why the concentration doesn’t change.
Solution
One way to change the volume without changing the concentration is by adding a solvent. A solvent is a substance that dissolves a solute (a chemically different liquid, solid or gas), resulting in a solution.
Here are the steps:
-
Identify the solvent in the solution. The solvent is the substance that is present in the greatest amount.
-
Add more of this solvent to the solution. This will increase the volume of the solution.
-
The amount of solute in the solution remains the same. Therefore, the concentration (the amount of solute per unit volume) does not change.
The reason the concentration doesn’t change is because you are only adding more solvent, not solute. The concentration is determined by the amount of solute in a given amount of solution. If you add more solvent, the amount of solute doesn't change, so the concentration remains the same.
