Neutralisation

Neutralisation

Aim: To observe a neutralisation reaction.

Method: 

1. Get a test tube rack, 6 test tubes, acid, base and universal indicator.

2. Fill 4 test tubes with 3mL of acid.

3. Fill 2 test tubes with 3mL of base.

4. Add a squirt of universal indicator to each.

5. Add different amounts of acid and base to make the colours of the rainbow (ROYGBI)

Results: 

Discussion: 

We started with 4 red test tubes and 2 blue test tubes, but by the end of the experiment we ended up with  colours of the rainbow (ROYGBI). We did this by neutralizing some of the acid by adding base into it to make orange, yellow, and green. For the 1 of the base we add acid to make it a lighter shade of blue. 

Conclusion:

This experiment did work because we were able to neutralise the acids and bases to make the colours of the rainbow.
