CaCl2aq

CaCl2aq refers to an aqueous solution of calcium chloride. Calcium chloride (CaCl2) is an ionic compound composed of calcium cations (Ca2+) and chloride anions (Cl-). When dissolved in water, these ions dissociate and become hydrated by water molecules, forming a homogeneous solution.

Aqueous solutions of calcium chloride are commonly used in various applications. One prominent use is as a de-icing agent on roads and sidewalks due to its ability to lower the freezing point of water. It is also employed in food processing as a firming agent, particularly in canned fruits and vegetables, and as an electrolyte source in sports drinks. In industrial processes, it can be used in concrete acceleration, as a desiccant, and in the production of other chemicals.

The concentration of CaCl2 in an aqueous solution can vary significantly, impacting its properties such as freezing point depression and osmotic pressure. These solutions can range from dilute to highly concentrated. The dissolution of calcium chloride in water is an exothermic process, meaning it releases heat. When handling concentrated solutions, caution should be exercised as they can be corrosive and irritating to skin and eyes.
