Science Expirement (Neutralisation)

Aim: To observe a neutralization reaction

Equipment: Test tube, Test tube rack, Ammonium Hydroxide, Sulfuric Acid, dropper or dropper battle,  Universal indicator solution

Method: Add approximately 1-2 mL of Ammonium Hydroxide and place the test tube into the test tube rack. Add
3-5 drops of Universal indicator solution. Using a dropper bottle, add Sulfuric acid drop by drop. Be careful because adding even a small amount of extra acid can mean you´ll miss the neutralisation.

Observations: Universal indicator turned blue when you put sodium carbonate solution. When you put acid it'll make some bubbles. When you add too much acid the colour changed to yellow, green and red.
