Here at Precision Laboratories, we’re all about chemistry, and you might have noticed from our wide range of pH test strips that we’re obsessed with pH. From our most basic litmus papers to our narrow-range plastic pH test strips, we’ve got you covered. But sometimes, it’s just more fun to see some exciting acid base reactions, like an erupting volcano or dancing raisins, so here are 50 acid base reaction experiments for you to try at home!

Many of these experiments involve reactions between baking soda and vinegar, which are common household ingredients. Baking soda is alkaline, and has a pH of 9.0, while vinegar is acidic and has a pH of about 3.0. Other experiments use similar ingredients, like citric acid, to get a reaction. Get ready for some fun when you start experimenting with the pH scale!
