Step-by-step explanation:
The drying agent that has a high capacity, reasonable efficiency, and works quickly is called silica gel.
Silica gel is a porous form of silica that can absorb and hold a large amount of moisture. It is commonly used as a drying agent in various applications, including preserving moisture-sensitive items like electronics and food products.
For example, silica gel packets are often found in packaging for products like shoes or vitamins to keep them dry and free from moisture damage. Silica gel works quickly to remove moisture from the surrounding environment because of its high capacity and efficient absorption properties.
