Lab Activity: Acid and pH Levels

Please view the video demonstration of this lab which can be found at the bottom of the post.

This is an easy lab you can do at home with minimal equipment! You will need some litmus paper or pH paper - you can get that at a teacher supply store or through a company who sells science equipment (such as Delta or Nasco).


If you have time, try to gather samples of rain water or pond water from your area.

Use the litmus or pH paper to measure the pH levels of common substances. This could include lemon juice, tap water, vinegar, soda, and liquid soap.

Create a simple chart on a piece of paper to record your results.


Which substances were most acidic? Most basic?
