A science class favorite, this package of 100 pH test papers lets you learn about acids and bases. Chemical reactions cause the paper’s color to change when exposed to varying levels of acid and base. This color change can be matched against the 1-14 scale color chart provided to determine the pH of the solution at hand.
More than just a lab experiment, recent studies have shown the pH of the body is important to one’s overall health and well being. This pH test paper can also be used on collected samples of your own bodily fluids (saliva, urine) to determine your pH.
