Its ability to absorb moisture makes it useful in several commercial applications. It is used as a desiccant, a drying agent, to prevent liquids from freezing, in salt water aquariums and in fire-extinguishers. It is also used in prepared foods to enhance salt flavour without increasing sodium.
Calcium chloride breaks down easily in water, forming calcium and chloride ions. Calcium promotes plant growth and chloride is an important micronutrient for plants and plays a role in photosynthesis.
