How to Test the pH of a Substance
- 1). Pour the liquid or substance into a beaker or a glass. If you are working with a hazardous substance, make sure you are wearing goggles, an apron and gloves for protection.
- 2). Dip the litmus paper in the liquid. The litmus paper should be wet, but you do not need to soak it.
- 3). Compare the color of the wet litmus paper to the color chart that was included with the litmus paper. The color chart provided by the litmus paper manufacturer will help you determine the pH of your substance.
