Description

Description: Calcium Chloride Flakes

Calcium chloride is an ionic compound of calcium and chlorine. It is highly soluble in water and it is deliquescent. It is a salt that is solid at room temperature, and it behaves as a typical ionic halide. It has several common applications such as brine for refrigeration plants, ice and dust control on roads, and in cement. It can be produced directly from limestone, but large amounts are also produced as a by-product of the Solvay process. Because of its hygroscopic nature, it must be kept in tightly sealed containers.

Calcium chloride is used to increase the water hardness in swimming pools. This reduces the erosion of the concrete in the pool. In marine aquariums, calcium chloride is added to introduce bio-available calcium for calcium carbonate-shelled animals such as mollusks and some cnidarians. Calcium hydroxide (kalkwasser mix) or a calcium reactor can also be used to introduce calcium, however calcium chloride addition is the fastest method and has minimal impact on pH.

Key Properties:

  • Calcium chloride can be found in solid state at room temperature, and is available as flakes, granules and powdered form.
  • Calcium chloride is salty to taste. Hence, it is added to many food products like canned vegetables, pickles etc.
  • In solid form, calcium chloride is white in color, while in liquidated form, it is colorless.
  • Usually in a molten state, it is a good conductor of electricity.
  • Calcium chloride is a bad conductor of heat.
  • Its boiling point is as high as 1600 C.
  • It is soluble both in inorganic solvents like water, as well as organic solvents like ethanol.
  • It absorbs moisture from air. If exposed to open air, it tends to become liquid. That is why, it is often called a deliquescent substance.
  • It has a low melting point, which means it can be dissolved at a very low temperature.
  • Calcium chloride is exothermic in nature, that is, it releases heat during any chemical reactions.
  • When calcium chloride is exposed to water, a large amount of heat is liberated, which can cause sputtering and boiling. The end product of this reaction is calcium hydroxide and chlorine gas.
