Calcium chloride (CaCl2) is a deliquescent salt, which means that it turns to water by absorbing moisture in the air.

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.

Calcium chloride is not hazardous and can be disposed of in the trash or down the drain.

If calcium chloride is dissolved in water, after being used as a container desiccant for example, dilute it down to 1% or less. Turn on the faucet and pour the diluted solution down the drain. Follow with water for five minutes.

Nordic Power Desiccant uses calcium chloride as an absorbent. It is therefore non-toxic and environmentally friendly.

What’s the difference between absorption and adsorption and sorption?

The terms absorption and adsorption are used freely to indicate the same process of taking moisture from the air using desiccants, mostly because we don’t want to complicate the explanation of what our product does. But there is a difference.

Absorption generally refers to two phenomena which are largely unrelated. In one case, it refers to when atoms, molecules, or ions enter some bulk phase – gas, liquid or solid material. For instance, a sponge absorbs water when it is dry.

Absorption also refers to the the process by which the energy of a photon is taken up by another entity, for example, by an atom whose valence electrons make transition between two electronic energy levels. The photon is destroyed in the process. The absorbed energy may be re-emitted as radiant energy or transformed into heat energy. The absorption of light during wave propagation is often called attenuation. The tools of spectroscopy in chemistry are based on the absorption of photons by atoms and molecules.

Adsorption is similar, but refers to a surface rather than a volume: adsorption is a process that occurs when a gas or liquid solute accumulates on the surface of a solid or, more rarely, a liquid (adsorbent), forming a molecular or atomic film (the adsorbate). It is different from absorption, in which a substance diffuses into a liquid or solid to form a solution.  This is what happens to calcium chloride desiccants in container shipments.

Sorption encompasses both processes, while desorption is the reverse process.
