Calcium Chloride is a salt with high solubility in water that is solid at room temperature, this chemical who is known by the chemical formula CaCl2 is a colorless crystalline.
It is dissolves in water. Producing chloride and the aquo complex [Ca(H2O)6]2+. In addition, these solutions are sources of “free” calcium and free chloride ions. These solutions react with phosphate sources to give a solid precipitate of calcium phosphate
CaCl2 has a very high enthalpy change of solution, indicated by considerable temperature rise accompanying dissolution of the anhydrous salt in water. This property is the basis for its largest scale application.
Molten cacl2 can electrolysed to give Ca metal and Cl gas.
Calcium chloride grades:
CaCl2 categorized in to main grades with different uses, specification and properties.
pub-ltd is the producer of calcium chloride, a premium salt with a variety of beneficialapplications including drilling fluid, ice control, dust suppression, road stabilization and oilfield services.
It made for more than 100 years. It mostly apply to control snow and ice on sidewalks, parking and roads. Suppresses dust on unpaved surfaces and roads. In addition, it has innovative applications, such as oilfield operations, industrial processing, agriculture, water treatment, refrigeration systems and tire weighting.
CaCl2 brine extracted from natural stock about 0/5 mile under ground. Then it processed, purified and manufactured as a variety of solid and liquid products with dozens of important and beneficial uses. It`s an industrial product with huge usages in Various industries.
food grade :
The average intake of calcium chloride as food additives has been estimated to be 160–345 mg/day that is use in organic crop production is generally prohibited under the US National Organic Program.
In marine aquariums, calcium chloride is one way to introduce bio-available calcium for calcium carbonate-shelled animals such as mollusks and some cnidarians.
It`s a firming agent used in canned vegetables, firming soybean curds in tofu and producing caviar swap from vegetable or fruit juices. It also uses in sports drinks and beverages.
Sorely salty taste of cacl2 causes to flavor pickles without gaining food’s sodium content. It’s freezing-point depression properties apply to slow the freezing of caramel in caramel-filled chocolate bars. CaCl2 also added to sliced apples to maintain texture.
In brewing beer, calcium chloride is sometimes applies to correct mineral deficiencies in the brewing water. It affects flavor and chemical reactions during the brewing process, and can also affect yeast function during fermentation.
In cheese factories, sometimes it added to processed (pasteurized/homogenized) milk to restore the natural balance between calcium and protein in casein. It`s added before coagulant. By spraying on the tree during the late growing season it prevent cork spot and bitter pit on apples.
