Molarity and the Principle of Dilution
A student dilutes 50.00 mL of a 1.00 M acid solution by adding water to a final volume of 250.00 mL. The resulting concentration is 0.200 M. Which of the following statements best explains this observation?
A
The dilution decreases the acid concentration to 0.200 M, as the number of moles remains constant while the volume increases.
B
The final concentration of 0.200 M indicates an error in the dilution procedure since the initial concentration should be maintained regardless of dilution.
C
The reduction in concentration to 0.200 M implies that a significant portion of the acid was lost during the dilution process.
D
Dilution should not alter the concentration; therefore, the final concentration should still be 1.00 M.
