Calcium Chloride
In this topic, we will be learning about Calcium chloride, Calcium chloride anhydrous, or Calcium dichloride. It is an ionic compound that comprises two ions i.e calcium and chlorine,(Calcium and Chlorine formula are Ca²⁺ and Cl⁻ respectively). The chemical formula for calcium chloride is CaCl₂. This inorganic compound is a white-colored crystalline solid, odorless, and is highly soluble in water.
Properties of Calcium Chloride
Uses of Calcium Chloride
It is used as an electrolyte in sports drinks and other beverages, including bottled water.
Due to its ability to absorb moisture, Calcium chloride is often found as a firming agent in foods.
Used as a Food additive, Food preservatives, in Dye, Paint industries, etc.
It is often used in concrete mixing because it simultaneously speeds upsetting the concrete while reducing the effects of moisture on the mixture.
It is also used in water treatment plants, and as a brine in refrigeration plants.
It also has medicinal qualities. It is used in lowering blood pressure and treating acid burns.
Structure and Chemical Formula for Calcium Chloride
[Image will be Uploaded Soon]
As discussed, The chemical formula for calcium chloride is CaCl₂. It is an ionic compound made of ions.
It consists of Calcium cation Ca²⁺ and Chlorine anion Cl⁻. Calcium chloride is mainly produced by the reaction of limestone (CaCo₃) with hydrochloric acid (HCl).
calcium chloride equation: CaCo₃ + 2HCl → CaCl₂ + CO₂ + H₂O(aq)
Did You Know?
If ingested directly, Calcium chloride can cause some serious health issues. It can lead to burns in the mouth and throat, vomiting, stomach pain, low blood pressure, and other possible severe health effects.
It can irritate the skin by causing excessive dryness.
FAQs on Calcium Chloride Formula
Question: Write the Chemical Formula of Calcium Chloride and Its Properties.
Answer: The chemical formula for calcium chloride is CaCl₂.
Properties: It is water-soluble, hygroscopic, and deliquescent. It absorbs enough water to turn into liquid. Also, it dissolves in water in a very exothermic manner with the release of a large amount of heat. It can fully dissociate in water to give both ions.
Question: Calculate the Molar Mass of CaCl₂
Answer: CaCl₂ chemical name is Calcium Chloride and the molar mass of Calcium is 40.08 grams and molar mass of Chlorine is 35.45 grams. So the molar mass of Calcium Chloride can be calculated as:
40.08 + 2 x 35.45
= 110.98 gm/mol.
Question: What Happens When Anhydrous CaCl₂ is Exposed to Air for Some Time.
Answer: CaCl₂ compound name is Calcium Chloride, It will absorb a sufficient amount of water from the air to allow it to dissolve. Anhydrous calcium chloride is deliquescent that is why it will turn colorless when exposed to air. (Deliquescence is the process through which a substance absorbs moisture from the atmosphere till it dissolves in the absorbed water and forms a solution.)
