Titration Curve: Weak Acid–Strong Base Shape
Captions available
The idea
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.
In practice
Titrating acetic acid with NaOH crosses its equivalence point near pH 8–9, not pH 7.
Where people slip
Expecting every equivalence point at pH 7 ignores that the salt's own hydrolysis sets that point.
