- Equivalence point: point in titration at which the amount of titrant added is just enough to completely neutralize the analyte solution. At the equivalence point in an acid-base titration, moles of base = moles of acid and the solution only contains salt and water.

They look for an “equivalence point,” the point at which enough titrant has combined with the analyte to neutralize it. At this specific point, the amount of titrant in the system reveals the amount of analyte in the system; the moles of both species equal one another.
Nov 13, 2022 · Sketch out a plot representing the titration of a weak monoprotic acid by a strong base, or of a weak base titrated by a strong acid. Identify the equivalence point and half-equivalence points. Explain what an acid-base indicator is, and how it works.
Define equivalence point. Describe how to perform a titration experiment. Perform calculations to determine concentration of unknown acid or base. Describe titration curves of acid-base neutralization reactions.
Jun 29, 2017 · The equivalence point of an acid–base titration is the point at which exactly enough acid or base has been added to react completely with the other component. The equivalence point in the titration of a strong acid or a strong base occurs at pH 7.0.
The equivalence point of a titration is the point at which 'chemically equivalent' amounts of acid and base have been mixed. Equivalence points are not always pH 7. An indicator that changes colour at a pH very close to the equivalence point must be used in a titration.
Encyclopedia. Equivalence point or stoichiometric point occurs during a chemical titration when the amount of titrant added is equivalent, or equal, to the amount of analyte present in the sample. In some cases there are multiple equivalence points which are multiples of the first equivalent point, such as in the titration of a diprotic acid.
