Titration

Meaning in chemistry, with examples

/taɪˈtreɪʃn/nounCore term

In chemistry, titration means: A method for finding the unknown concentration of a solution by adding a solution of known concentration from a burette until the reaction between them is just complete.

In Turkish: titrasyon

How it is used

A classic teaching experiment and a routine quality-control method. You do or run a titration, 'titrate the sample with NaOH', record the burette readings and repeat until two results agree closely.

Example sentences

  1. We did three titrations and the results agreed within 0.1 mL.

  2. Use phenolphthalein as the indicator for this titration.

Common collocations

  • acid–base titration
  • carry out a titration
  • back titration
  • titration curve
  • titrate with
  • buretteA long, graduated glass tube with a tap (stopcock) at the bottom, used to add a liquid gradually and measure exactly how much was added, mainly in titrations.
  • endpointThe point in a titration where the indicator changes color or the signal changes sharply, showing that the reaction is complete and you should stop adding titrant.
  • indicatorA substance that changes color at a certain pH or at the end of a reaction, used to show when a titration is complete. Phenolphthalein and methyl orange are common examples.
  • standard solutionA solution whose concentration is known accurately. It is used to find the concentration of other solutions in titrations or to build calibration curves.
  • neutralizationThe reaction between an acid and a base that produces a salt and water and brings the pH closer to 7.
