APFIVE Which of the following conclusions is best supported by the evidence that diluting 50.00 mL of a 1.00 M acid to a total volume of 250.00 mL results in a final acid concentration of 0.200 M?
| Dilution Data |
| Stock Solution: 1.00 M acid |
| Aliquot Taken: 50.00 mL |
| Final Volume After Dilution: 250.00 mL |
|---|
Dilution should not alter the concentration; therefore, the final concentration should still be 1.00 M.
The dilution decreases the acid concentration to 0.200 M, as the number of moles remains constant while the volume increases.
The reduction in concentration to 0.200 M implies that a significant portion of the acid was lost during the dilution process.
The final concentration of 0.200 M indicates an error in the dilution procedure since the initial concentration should be maintained regardless of dilution.
