Neutralisation
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:
1. Add approximately 1-2ml of NA2CO3 and place the test tube into the test tube rack. Add 3-5 drops of Universal indicator 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 neutralization point.
Observation:
The only change that does produce something different during the neutralization is the reaction between hydrogen ions and hydroxide ions, which produces water molecules. This is the ionic equation that represents the neutralization reaction between an acid and an alkali. When we did it started off at a ph of 0 but when we added sodium carbonate it went to a ph of 12-14.
