Science: Neutralisation

Science: Neutralisation

Aim: To observe a neutralisation reaction.

Equipment:

•  test tube
• test tube rack 
• Sodium Hydroxide
• Hydrochloric Acid
• Universal Indicator solution
• dropper bottle 

Method:

Add approximately 1-2 ml of Solution Hydroxide and place the test tube in the test tube rack. Add 3-5 drops of Universal indicator solution. 

Using a dropper bottle add the Hydrochloric acid. Be careful because adding even a small amount of extra acid can mean you'll miss the neutralisation point.

Result: 

After adding the hydrocloric acid we notice that the solution make it turn green after mixing a little longer it then turned yellow. So that meant we had to add more Hydroxide to make the green we wanted. Once it turned green we were able to get an neutrolise  point.

Discussion: 

We quickly noticed that adding a slight drop changed the colour dramatically. So we had to take our time and do it drop by drop. When we finally got a green colour we didn't think it was the best so we kept putting more drops to get the right colour we were looking for. We wanted to make the solution green because green equal neutralisation. Neutrolisation is basically equivalent to water, it is a mixture of base and acid together which make it green and its technically a nice and calm solution. I wouldn't recommend drinking it, its not completely harmless but it not entirely harmful. 

Conclusion  

At first putting one single drop we realised that its gonna take a little bit of time to get the right green we are looking for. That meant we had to experiment with the chemicals and do it drop by drop. We also had to keep in mind how much of the different chemical drops we put in so nothing will overpower anything. After a while of messing around we were able to finally get the right solution/green we were looking for.
