Calcium chloride formula, also known as Calcium dichloride formula or Calcium chloride anhydrous formula, is given in this article. This inorganic compound is a white powder or white coloured crystalline solid, odourless, and is highly soluble in water. It is an ionic compound comprising of calcium and chlorine. There exist one calcium cation and two chlorine anion in the structure of calcium chloride. At room temperature, it is a solid salt which acts as an ionic halide. The chemical or molecular formula for calcium chloride is CaCl2. It can be naturally obtained from sinjarite and antarcticite in its hydrated form. Also, it is found in brine from salt deposits and salt lakes. Commercially it can be produced directly from limestone, and a large amount is also generated as a by-product from the Solvay process.

Properties Of Calcium Chloride Formula

The chemical formula of calcium chloride is CaCl2. Calcium chloride is hygroscopic, deliquescent, and dissolves in water exothermically.

Chemical formula CaCl2
Molecular weight 110.98 g/mol
Density 2.15 g/cm3 anhydrous
Melting point 772–775 °C anhydrous
Boiling point 1,935 °C anhydrous

It is widely used as brine for refrigeration plants, to replenish calcium levels, as an antidote for magnesium poisoning, and as an acid-producing diuretic. When in calcium chloride comes in contact with skin it acts as an irritant by drying the moist skin. Ingesting it can cause burns in the mouth and oesophagus.

Practise This Question

Imagine a gravity free laboratory, in outer space, where you are asked to study the motions of a large number of marbles kept in a transparent cubical jar, as you give the jar quick, small jerks in random directions. You will observe, that after giving a sufficient number of jerks, the marbles start moving rather chaotically, i.e., each marble bounces off other marbles every now and then, and takes a random trajectory between two points due to these collisions. You seem to have given some kinetic energy to each marble, when the jar was being shaken. What happens when you release the jar suddenly, leaving it suspended in space? Assume all collisions between the marbles to be perfectly elastic.
