Prepare a mixture by dissolving 1 g of experimental soap bar in a10 mL distilled water (preferably a neutral liquid). Dip one strip of pH paper in the previously prepared mixture. The pH paper will then change its color. Find a color that matches with the chart that comes along with pH indicator package.
The scale of the chart ranges from 1-14. Below 7 is said to be acidic and above it is alkaline or basic.
Picture shows that the change in color of the strip matches on a 12th scale. Therefore the pH is 12 and the soap is alkaline.
