Neutralisation Experiment

   Neutralisation
 A chemical reaction occurs when you mix together an qcid and base.The base cancels out tge effect of the acid. The reaction called a neutralisation reaction because a neutral solution is made if you add just the right amount of acid and base together.

 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 a dropler bottle, Universal indicator solution.

Method:
 1st step - add approximately 1-2 mL of Na2CO3 and place the test tube into the test tube rack. Add 3-5 drops of Universal indicator solution.

2nd step - 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 neutralisation point.

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