Aim: To observe a neutralization 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 botle, Universal indicator solution.
Method:
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.
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.
Results:
This was a cool experiment cause we get to see colors changing but it was hard to get one fully green. But we did make a multi-colored one which was worth it. The color would turn red if it was too much acid and it would be violet if it was mostly base.
Conclusion: Cool experiment and all but hard to make it turn green. Didn't really take long to do.
