Neutralisation

Aim: To observe a neutralisation reaction.

Equipment: Test tube rack, test tube, 1 mol L-1 Na2CO3 (sodium carbonate), 1 mol L-1 HCI (hydrochloric acid), dropper or dropper bottle, universal indicator solution.

Method:

1. Add approximately 1-2 mL of NaCO and place the test tube into the test tube rack. Add 3-5 drops of Universal indicator solution.
2. Using a dropper bottle, add HCI drop by drop. Be extra careful because adding even a small amount of acid can mean you'll miss the neutralisation point.

Results:

Discussion:

As we were doing our experiment, our work succeeded and turned neutral, as we finished our neutralisation, we tried to mix some things altogether, as a result, we came up with a rainbow-like effect into a single Testube.
