Titration Practical

The experiment for determining the reacting volumes of a strong alkali and a strong acid by performing a titration is:

Method

Using a pipette, add a set volume of a strong alkali to a conical flask.
Add a few drops of a suitable indicator.
Place a strong acid (sulfuric, hydrochloric or nitric acid) of known concentration in a burette.
Take an initial reading of the volume of acid in the burette.
Gradually add the acid to the alkali. Make sure that you are regularly swirling the conical flask as you add the acid. As you get closer to the end point, start to add the acid at a slower rate.

Method continued

As soon as the indicator changes colour, stop adding acid.
Take a final reading of the volume of acid in the burette.
Subtract the final reading from the initial reading to calculate the volume of acid needed to neutralise the alkali.
