Acids, Bases and Indicators

Science

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:
