Chemistry Required Practical: Neutralisation Experiment

GCSE Chemistry Required Practical - Neutralisation Experiment

To investigate the change in pH when adding powdered calcium hydroxide to a fixed volume of dilute hydrochloric acid.

1. Use a measuring cylinder to add dilute hydrochloric acid to a beaker.
2. Dip a clean glass rod into the contents of the beaker. Use it to transfer a drop of liquid to a piece of universal indicator paper on a white tile. Wait 30 seconds, then match the colour to a pH colour chart. Record the estimated pH.
3. Add a level spatula of calcium hydroxide powder to the beaker.
4. Stir thoroughly, then estimate and record the pH of the mixture (as in step 2).
5. Repeat steps 3 and 4 until there are no more changes in pH.
