Widely used as a desiccant, silica gel absorbs moisture to protect products from humidity damage. It is commonly found in packaging for electronics, pharmaceuticals, and food to extend shelf life and prevent mold or corrosion. In laboratories, it serves as a drying agent for gases and liquids. Silica gel is also used in chromatography for separating compounds due to its adsorption properties. In industrial settings, it helps dry air and natural gas streams. Some forms are used in cat litter for odor control and moisture absorption. Indicator silica gel changes color when saturated, allowing visual monitoring in moisture-sensitive environments.
