Question

If an equal number of moles of a strong base and a weaker acid are mixed together, what would you expect the pH of the resulting solution to be? a) pH = 7, because an acid and base neutralization always makes a neutral pH b) pH = 0, because the pH has been used up c) pH higher than 7, because there will be fewer [H+] than [OH-] d) pH lower than 7, because there will be fewer [OH-] than [H+]

          If an equal number of moles of a strong base and a weaker acid are mixed together, what
would you expect the pH of the resulting solution to be?
a) pH = 7, because an acid and base neutralization always makes a neutral pH
b) pH = 0, because the pH has been used up
c) pH higher than 7, because there will be fewer [H+] than [OH-]
d) pH lower than 7, because there will be fewer [OH-] than [H+]

Step 1

This is because the strong base will completely dissociate, while the weak acid will only partially dissociate. The excess hydroxide ions (OH-) from the strong base will make the solution basic, resulting in a pH greater than 7. Show more…
