Application of Calcium Chloride
Calcium chloride is often found as a firming agent in foods, due to its ability to absorb moisture. It helps hold canned vegetables together, and to convert soy curd into solid blocks of tofu. Further, it can depress freezing levels in liquids and semi-solids, making it useful in the creation of cold foods such as ice cream.
In addition, it can also be found as a flavor additive. It has an extremely salty flavor and can, therefore, be used as an alternative to standard salt, such as in “low sodium” products. It even functions as an electrolyte in many sports beverages.
Calcium chloride is an extremely common additive to soft water, particularly in swimming pools and other situations where water is being held in concrete. The calcium leeches into the concrete, preventing erosion.
Calcium chloride also has many applications in the medical industry. In medications, it can function as a buffering agent, as well as an anti-moisture agent. It has direct medicinal qualities as well. It is utilized in lowering blood pressure, as well as treating acid burns. Injections may also be used to enhance the resolution of an electrocardiogram.
Calcium chloride is frequently utilized as a de-icing agent and is very often what’s actually in municipal “salt trucks” de-icing roads in the winter. However, it was probably also utilized in the creation of the road itself! Calcium chloride is often utilized in concrete mixing, because it simultaneously speeds up setting of the concrete, while also reducing the effects of moisture on the mix.
5.De-icing and freezing-point depression
By depressing the freezing point of water, calcium chloride is used to prevent ice formation and is used to de-ice. This application consumes the greatest amount of calcium chloride. Calcium chloride is relatively harmless to plants and soil. As a deicing agent, it is much more effective at lower temperatures than sodium chloride. When distributed for this use, it usually takes the form of small, white spheres a few millimeters in diameter, called prills. Solutions of calcium chloride can prevent freezing at temperatures as low as −52 °C (−62 °F), making it ideal for filling agricultural implement tires as a liquid ballast, aiding traction in cold climates.
