science

Aim: To observe a neutralisation reaction.

Equipment: A test tube, test tube rack, 1 moL L-1 Na2CO3 (Sodium Carbonate), 1 mol L-1 HCI (Hydrochloric Acid), dropper or dropper bottle, (Universal indicator solution.

Method

Add approximately 1-2 mL of Na2CO3 and place the test tube into the test tube rack. Add 3-5 drops of Universal Indicator solution.

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: What happened was we used substances then use universal indicator solution in the substances to see the colours to tell if it was basic or acid.

Conclusion: It was cool and it worked cause we saw lots of colours
