The Science Behind Calcium Chloride Dissolving in Water
One of the most useful substances, calcium chloride (CaCl₂), has uses in food preparation, industry, agriculture, and road safety. Its behavior in water is one of its most intriguing characteristics. There are many useful uses for this simple act of dissolving, which sets off an intriguing chemical reaction that generates heat. Let us examine the science to see why SNDB is the world’s leading seller, supplier, and exporter of calcium chloride.
What Happens When Calcium Chloride Dissolves in Water?
Heat escapes during a strongly exothermic reaction that occurs when CaCl₂ comes into contact with water. This happens when calcium (Ca²⁺) and chloride (Cl⁻) ions enter the solution due to the breaking of the ionic bonds in CaCl₂.
Chemical Equation:
CaCl₂ (s) → Ca²⁺ (aq) + 2Cl⁻ (aq)
Dissolution of Calcium Chloride in Water

As the solid salt dissolves:
- 1. It is hygroscopic, meaning it absorbs moisture.
- 2. The energy release (heat) enables the water to feel significantly warmer.
Why Is This Reaction Important?
- De-icing and Dust Control: On highways, the heat produced aids in the rapid melting of snow and ice.
- Concrete Acceleration: In cold weather, it accelerates the setting time in construction.
- Desiccant Applications:
- Food Industry: It is used to firm vegetables, make cheese, and brine them.
