Indicator paper comes in form of strips that have been dipped in a a halochromic chemical compound, which helps in visual determination of the magnitude of acidity and alkalinity of pH of the given solution. The universal paper indicators are laced with a solution of varied compounds that exhibit varied smooth color transitions on exposure to acidic and alkaline solutions over a pH range of 1 to 14.

Although there are various forms of indicator paper commercially available in the market, all of them have more or less the same formula
