A titration is a process by which a solution of known concentration is quantitatively added to a solution of unknown concentration in order to determine its concentration. You will be using burets to perform the titrations. The titration end point or equivalence point is when stoichiometrically equivalent amounts of the two substances are present.

The first is performed by quenching an aliquot of the solution into water and titrating the hydroxide produced with 1 m acid, using phenolphthalein or bromocresol purple as an indicator. This method has the disadvantage that it does not discriminate between the organometallic and hydroxide ion that may be present in the solution from its.
