Drying agents are substances used to remove moisture from liquids or gases. They work by absorbing water, helping to keep materials dry and preventing unwanted reactions caused by humidity. Common drying agents include silica gel, calcium chloride, and magnesium sulfate. These agents are often used in laboratories, packaging, and various industrial processes. In addition to their use in scientific and industrial applications, drying agents are also found in everyday products. For example, silica gel packets are commonly included in shoe boxes and food packaging to keep items dry. Proper use of drying agents can enhance product longevity and maintain quality.
