Once you have determined if a substance is an acid or a base, you need to determine how strong (or concentrated) it is. The simplest measure of the strength of an acid or base is the concentration of H+ ion in the solution. The fastest way to determine pH is to use pH paper. It uses a broad range indicator to turns a series of colors from pH 1 to 14. The color change is then compared with a color chart to determine the pH. A high pH indicates a base, and a low pH indicates an acid. A pH near 7 indicates a neutral substance. Peoples should be aware that shampoos and soaps and most skin products are pH balanced near 7, to protect skin, hair and eyes..
