Introduction to Titration
▶︎ Watch it animatedinteractive step-through · ~3 min · optionalA titration finds an unknown concentration by adding a titrant of known concentration until the reaction is complete. The equivalence point is when the moles of titrant and analyte match the balanced equation's stoichiometric ratio; an indicator's endpoint (a color change) is used to estimate it.
The misconceptions treat titration as simpler than it is: assuming equal volumes mean equivalence, conflating the endpoint with the true equivalence point, defaulting to a 1:1 ratio, or thinking a stronger titrant implies more analyte. The stoichiometric ratio and the moles, not volumes alone, decide equivalence.

Titration reaches equivalence when moles match the stoichiometric ratio, estimated by the indicator endpoint. The lesson works the mole reasoning, then closes with a ten-scenario check.
