Acids, Bases and Indicators
Aim: To investigate how indicators change colour in acids and bases.
Method:
1. Set up your spotting tile with two drops of acids in the first row of four, two drops of water in teh middle row of four and then 2 drops of base in the last row of four.
2. In the first row of three put a small piece of red litmus paper (tear your strip into three for this), in the second row put a small piece of blue litmus paper, in the third row a small piece of universal litmus paper and in the fourth a drop of universal indicator.
3 Take a photo of your spotting tile and insert it here:
Conclusion: Different acids and bases don't change the paper into the same colour a lot of the time.
