Test the acidity of common substances using pH paper. Materials including soap, lemon juice, milk, and oven cleaner can be tested by comparing the color of pH strips to a standard scale. Some are going to be in between two numbers, but that's alright. Choose between 19 different substances and click "Test" to find out their acidity. Click "Reset" to reset the whole thing, making you able to change substances again. Enjoy.
FEATURED - 10/13/2023. THANK YOU SO MUCH! After a lot of hard work and a lot of testing, it's finally done. Thumbnail and idea by ExploreLearning. Everything else by me. Comment anything you would like to see in a new update, and you will get credit. -Updates- Added a section on the history of the pH scale and who invented it. Moved the button to close the information slide to the left in case I make another slide, I can add an arrow to change slides.
