Frequently Asked Questions
What is titration?
Titration is a lab technique where a solution of known concentration (titrant) is added to a solution of unknown concentration (analyte) until the reaction is complete (equivalence point). At equivalence: MaVa × na = MbVb × nb.
What is the equivalence point?
The equivalence point is where stoichiometrically equivalent amounts of acid and base have reacted. For a strong acid + strong base, pH = 7 at equivalence. For weak acid + strong base, pH > 7 due to hydrolysis of the conjugate base.
What is back titration?
Back titration adds a known excess of reagent to the analyte, then titrates the unreacted excess. Used when the analyte is insoluble, reacts slowly, or when no suitable indicator exists for direct titration.
