Aim: To test the pH of a bunch of household chemicals.

Method: Add a few drops of each chemical to a spot on your spotting tile, Test the chemicals using litmus paper, Put a few drops of Universal Indicator to test the chemicals.

Results: Toilet cleaner in blue litmus paper was red, in red litmus paper it was red, in Universal Indicator it was red. Dish washing liquid in blue litmus paper it was blue, in red litmus paper it was blue, in Universal Indicator it was Green/Yellow. Floor cleaner in blue litmus paper was blue, in red litmus paper it was Indigo, in Universal Indicator it was red. Spray and Wipe in blue litmus paper was blue, in red litmus paper it was blue, in Universal Indicator it was blue.

Discussion: If the litmus papers go blue then that means the chemical you used was a base, if the litmus paper turns red then it means the chemical is an acid. Toilet cleaner is an acid because the litmus papers turned red when dipped into the chemical. Dish washing liquid is a base because the litmus papers turned blue when dipped into the chemical. Floor cleaner is a base because the litmus papers turned indigo when dipped into the chemical. Spray and wipe is a base because the litmus papers turned blue when dipped into the chemical.

Conclusion: The experiment went good because I have already done this before so it wasn't that complicated. I wouldn't do anything differently because its pretty simple on how we have done it and you don't want it to be overly complicated.
