Aim: To test the pH of a range of household chemicals.
Equipment: A variety of household chemicals, spotting tile,
red litmus paper, blue litmus paper, Universal indicator solution, safety glasses.
Method:
1. Add a few drops of each chemical to a spot on your spotting tile. If a substance is solid or powdered
you will need to mix it with a few drops of water before testing it.
2. Test the chemicals with litmus papers.
3. Test each chemical with a few drops of Universal indicator
If blue litmus paper turns into colour red, the solution is acidic. But if red litmus paper turns into blue, the solution is basic

| Here are the blue/red litmus paper and Universal indicator turned into. Some stayed as red and blue, then some turned blue to red, and red to blue. |
