science neutralisation

aim
to observe a neutralisation reaction

equipment
a test tube, test tube rack, 1 mol L-1  na2 co3 (sodium carbonate), 1 mol L-1 HCI (hydrochloric acid), dropper or dropper bottle, universal indicator solution

1. add approximately 1-2 ml  of na2 co3 and place the test tube into the testing 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 of extra acid can mean you'll miss the neutralisation point

observation

it will change a little bit
