Testing the pH of your soap is an easy way to be sure that your soap is safe to use, and doesn't contain any extra lye. The pH scale shows the strength of an acid or base. Soap with a high pH (above 10) is likely to be too harsh, or lye-heavy, for use.
To test a bar of soap's pH, wet the bar in running water and rub the bar with your hands until you get some bubbles or a thin film of liquid soap on the outside of the bar. Wet your litmus paper on it and check the reading.
