Question

Next, you will study how adding more solvent changes concentration. In the last problem, you measured the concentration of the concentrated solution to be [var:M2Drink] M. Make a prediction: What will happen to the molarity if 500 mL water is added to this solution? What will happen to the color of the solution?

Answer 1

Adding more solvent to a solution results in a decrease in the solution's concentration, and if the solution's color is related to the concentration, the color will become lighter after dilution.

Step-by-step explanation:

When you add more solvent to a solution, the concentration of that solution changes. Adding 500 mL of water to a molarity (M) of M2Drink M will result in a decrease in the molarity of the solution, as you are increasing the volume without changing the amount of solute in the solution. Using the dilution equation M1 × V1 = M2 × V2, where M1 and V1 are the initial molarity and volume, and M2 and V2 are the final molarity and volume post-dilution, we can calculate the new concentration after dilution. Regarding the color, if the solution's color intensity is related to concentration, adding more solvent would generally cause the color to become lighter as the solute becomes more diluted.
