State
A weak acid–strong base curve starts higher, buffers near half-equivalence, and reaches an equivalence point above pH 7, since the resulting salt hydrolyzes basic.
Show
Titrating acetic acid with NaOH crosses its equivalence point near pH 8–9, not pH 7.
Watch for
Expecting every equivalence point at pH 7 ignores that the salt's own hydrolysis sets that point.
