Titration Curve: Weak Acid–Strong Base Shape

This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.

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.
