A 50.0-mL sample of 0.50 M HCl is titrated with 0.50 M NaOH. What is the pH of the solution after 28.0 mL of NaOH have been added to the acid?
A)0.85
B)0.75
C)0.66
D)0.49
E)3.8

The correct answer is A because the pH of the solution after 28.0 mL of NaOH have been added to the acid is 0.85. This is because the reaction between HCl and NaOH is a neutralization reaction, which produces water and salt. The pH of the solution will increase as more NaOH is added, until it reaches a neutral pH of 7.0.
