Calcium Bromide

Calcium bromide is a chemical compound with the formula CaBr2. It consists of one calcium ion (Ca2+) and two bromide ions (Br-). The calcium ion has a 2+ charge, while each bromide ion has a 1- charge.

Calcium bromide is a white crystalline solid that is highly soluble in water. It has a melting point of 730°C and a boiling point of 806°C. It is hygroscopic, meaning it easily absorbs moisture from the air.

Calcium bromide is used as a source of bromide ions in various applications, such as drilling fluids, photography, and medicine. It is also used as a flame retardant in plastics and textiles.

In terms of its chemical reactivity, calcium bromide reacts with acids to form hydrobromic acid and with alkalis to form calcium hydroxide and bromide salts of the alkali metal. It also reacts with elemental chlorine to form calcium chloride and bromine gas.

Overall, calcium bromide is an important compound with many industrial and scientific applications.
