Key Stage 4

Meaning

Titration is an experimental technique used to measure the exact volumes of acid and alkali needed to have a complete Neutralisation reaction.

About Titration

During a titration one of the solutions is a fixed volume and the other is is added as needed and measured as precisely and accurately as possible.

To obtain a fixed volume a Volumetric Pipette is used.

To measure the volume being added a Burette is used.

Method

For a fixed volume of alkali and a measured volume of acid.

Wash the volumetric pipette and burette with distilled water then wash the volumetric pipette with the alkali and the burette with the acid to avoid contamination from previous experiments.
Measure and record a fixed volume of alkali using the volumetric pipette.
Add the alkali to a beaker and then add a few drops of pH Indicator.
Fill the burette with acid.
Add the acid to the alkali one drip at a time, swirling the beaker constantly to mix the reactants thoroughly.
Repeat until the pH Indicator shows the solution is neutral.
Record the volume of acid added to the beaker.
Repeat the experiment at least 3 times to produce an average.
