Neutralisation:
Aim: To observe a neutralisation reaction
Method:
1. Add approximately 1-2 mL of Na2CO3 and place the test tube into the test tube rack. Add 3-5 drops of Universal indictor solution.
2. Using a dropper bottle, add HCI drop by drop. Be careful because adding even a small amount of extra acid can mean you'll miss the neutralisation point.

Discussion:
Once we added the liquids we just played around with it until we got a certain colour or the rainbow, just like this photo here which is our results.
Conclusion:
In the end we got the results we wanted - Rainbow- and we also managed to get the colour green, which means it's neutral and is 6 -7 on the pH level.
