When utilizing a deliquescent drying agent, what is the primary function in the drying process?

The primary function of a deliquescent drying agent is to absorb moisture from the air, leading to its transformation into a liquid state. Deliquescent substances, such as calcium chloride or magnesium chloride, have the unique characteristic of drawing in water vapor and then dissolving in the water they absorb, consequently forming a solution. This process is particularly effective in maintaining low humidity in enclosed environments, such as instrumentation cabinets or storage areas.

While one might consider other processes like heat absorption or filtering particulates as relevant, they do not accurately reflect the primary utility of deliquescent drying agents. The focus of these agents is specifically on moisture control rather than altering physical states of materials by heat or performing filtration tasks.
