Acid-Base Titrations
A titration curve plots pH as titrant is added. The equivalence point is where the moles of acid and base match the stoichiometry — and it is not always at pH 7 (a strong-weak titration reaches equivalence at an acidic or basic pH). The half-equivalence point is where pH = pKa.
The traps assume the equivalence point is neutral (only strong-strong titrations reach pH 7), confuse the titration landmarks, and set equivalence by equal volume rather than matched moles. Read the curve by the mole relationships, not by pH 7 or equal volumes.

Titrations

A titration curve's equivalence point is set by moles (not always pH 7), and half-equivalence is where pH = pKa. The lesson reads the landmarks, then closes with a ten-scenario check.
Diagnostic
10-item topic check

Ten items spanning the Topic 8.5 misconceptions: the equivalence point assumed neutral, titration landmarks confused, and equivalence set by volume instead of matched moles.

Pick one of the failure modes you missed and drill it on its own. The round is adaptive: two correct in a row clears the misconception and moves you to the next.
