Acid-Base Titrations

AP Chemistry· difficulty 4/5

At the equivalence point of a weak acid–strong base titration, the pH is

  • A

    Greater than 7 (conjugate base is a weak base; hydrolysis raises pH)

    check_circle
  • B

    Exactly 7

  • C

    Less than 7

  • D

    Cannot be determined

Explanation

All weak acid is converted to its conjugate base, which hydrolyzes water to make the solution basic.
