Neutralisation experiment

In science, we have been learning about Acids and Bases. Chemical reactions occur when you mix together an Acid and a Base together. The base cancels out the effects of the Acid. This reaction is called Neutralisation because a neutral solution is made if you add just the right amount of Acid and Bases together. Chloe, Jess, Molly and I did an experiment exploring Neutralisation.

Neutralizing Acids and Bases

Aim:
To observe a neutralisation reaction by neutralising Sodium Carbonate using Hydrochloric Acid.

Equipment:
- Test tubes,
- Test tube racks,
- Sodium Carbonate,
- Hydrochloric Acid,
- Pipette,
- Universal indicator solution'

Method:
1. Add approximately 1-2mL of Sodium Carbonate into a test tube and place the test tube into the test tube rack. Add 3-5 drops of Universal Indicator solution.

2. Using a pipette, add Hydrochloric Acid drop by drop. Be careful because adding even a small amount of extra acid can mean you miss the neutralisation part.

Results: 

Here you can see that Chloe, Jess, Molly and I have created a rainbow using the Acids and Bases. The Red, Orange and Yellow liquids are all acidic. The red one has the strongest acidity. The two Blue liquids are both basic. The green liquid is the neutral liquid.

Discussion: 
During the experiment, we attempted to balance the colours in the Ph levels. The strongly acidic liquids are red and the strongly basic liquids are of a dark Blue colour. The universal indicator shows which level of the Ph scale it is. While doing this experiment, we quickly figured out that balancing these solutions is quite difficult. You have to mix the right amount of Acid and Base to balance the solution, then you add the universal indicator to see what level it is on the Ph scale. It is difficult to balance it perfectly as it can switch from one colour to another with a single drop of acid or base.

Conclusion:
In conclusion, our experiment was successful as everyone in our group somehow managed to neutralise the solution. We actually had a little race with Jessica as the winner. After that, Mr Heath challenged us to create a rainbow with the solutions.
