Equivalence Point vs. Endpoint Distinguished

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

State

The equivalence point is where moles of acid and base have exactly reacted, a stoichiometric fact; the endpoint is where the indicator visibly changes color.

Show

A well-chosen indicator changes color within a drop of the true equivalence point.

Watch for

The two are related but not identical — one is calculated, the other observed.
