Calcium chloride dihydrate is a chemical compound with the formula CaCl2·2H2O. It is a hydrated form of calcium chloride, which means it contains water molecules within its crystal structure. Calcium chloride dihydrate is a white, crystalline solid that is highly soluble in water. Here's an introduction to this product:

Chemical Composition:

• Calcium chloride dihydrate has the chemical formula CaCl2·2H2O, indicating that it contains one calcium ion (Ca²⁺), two chloride ions (Cl⁻), and two water molecules (H2O) per unit.

Physical Properties:

• Appearance:White, crystalline solid.
• Solubility:Highly soluble in water, and it releases heat when dissolved.
• Density:Varies with temperature and concentration, but typically around 1.85 g/cm³.
• Melting Point:Calcium chloride dihydrate does not have a sharp melting point but gradually loses its water content upon heating.
