[Chemistry Class Notes] on Calcium Chloride Formula Pdf for Exam

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

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.
