Calcium Chloride Formula:
- Calcium chloride is a common calcium salt that has many household and industrial applications. Calcium chloride is hygroscopic and dissolves in water exothermically. It is useful as brine for refrigeration plants, to replenish calcium levels and as an acid – producing diuretic.
- At room temperature it exists as a solid salt and it acts as an ionic halide. It is found in brine from salt deposits and salt lakes. Commercially, it can be produced directly from the limestone and a large amount is also generated as a by-product of the process.
- The chemical formula of calcium chloride is CaCl2
- It is an ionic compound consisting of the one Ca2+ and two chlorine anions Cl–. The bivalent calcium metal is forming an ionic bond with two chlorine atoms.
- Calcium chloride is an ionic compound. It is made of ions. As we know that ions can have positive or negative charge, but the overall charge of an ionic compound has to balance to get neutral.
- Calcium is in the group of 2 with +2 charge and chlorine is in group 7 with -1 charge. As the overall charge is 0 for neutral the charges must balance. Therefore one needs two chlorine ions to charge as 2-2 =0
- Calcium chloride is mainly produced by reacting limestone (CaCO3) with hydrochloric acid (HCl). The chemical equation is
CaCO3 + 2HCl CaCl2 + CO2 + H2 O(aq)
- It is also produced as a major product during the manufacture of soda ash by the solvay process, in which limestone is reacted with NaCl solution.
- It is an odorless white powder in the form of granules on flakes.
- Its density is 2.15 gram per ml.
- The melting points of 782 degrees C.
- It is highly water-soluble.
- It absorbs enough water to turn into liquid.
Calcium chloride has many uses. It is useful as a food additive, food preservative, for de-icing roads in winters, and as brine in refrigeration plants. It is also useful as a swimming pool chemical, in water treatment plants. Calcium chloride has many applications in metallurgy, oil-well drilling, and rubber, paper, dye and paint industries.
Calculate the molar mass of calcium chloride”
Formula of calcium chloride is CaCl2
The molar mass of calcium is 40.08 grams and the molar mass of chlorine is 35.45 grams. So the molar mass of calcium chloride will be:
40.08 + 2 35.45 = 110.98 gram per mole.
