In a glass if you are take 1.0 ml of a solution of HCl with a pH of 4.0 and add it to 9.0 ml of distilled water, what would be the pH of the final solution with detailed explanation?
A. The pH would remain unchanged.
B. The pH would rise to 5.5.
C. The pH would rise to 5.0.
D. The pH would be unmeasurable due to the amount of dilution.
E. The pH would rise to 7.0.
