Key Stage 4
Meaning
Find the volume of acid needed to neutralise an alkali using Titration.
Method
- Wash a volumetric pipette and burette with distilled water then wash the volumetric pipette with the 0.1M Sodium Hydroxide and the burette with 0.08M Sulphuric Acid to avoid contamination from previous experiments.
- Measure 25ml of Sodium Hydroxide using the volumetric pipette.
- Add the Sodium Hydroxide to a conical flask and then add a few drops of Methyl Orange.
- Fill the burette with 0.08M Sulphuric Acid.
- Add the Sulphuric Acid to the Sodium Hydroxide one drip at a time, swirling the conical flask constantly to mix the reactants thoroughly.
- Repeat until the Methyl Orange turns from yellow to red indicating the solution is Neutral (Chemistry).
- Record the volume of Sulphuric Acid added to the conical flask.
- Repeat the experiment at least 3 times to produce an average.
