  • Titrations
    • When solutions of and acid and an alkali react to form a salt and water, a neutralisation reaction occurs. The volumes of solutions that react exactly can be found by using a titration.
    • To do a titration, a pipette is used  to measure accurately the volume of alkali that is put into a conical flask. An indicator is added to the alkali. A burette is filled with acid, which is the gradually added to the flask.
    • When the indicator changes colour (methyl orange goes from being yellow in alkali to orange when neutral and red when acidic) the end point has been reached. The volume of acid added is found from the initial and final readings of the burette.
    • The titration should be done several times to improve the repeatablilty of the results.
