Chemical indicators function similarly to natural indicators. They are available for use as test strips made of paper, liquid suspensions and crystals. Chemical indicators are synthetic, meaning they are man-made, and do not occur in nature. These indicators are also useful for studying acid-base titrations, which use chemical indicators to reflect ranges of pH levels.
