Calcium Bromide

Chemical Formula

The chemical formula of the calcium bromide is CaBr2. It has consists of one calcium and two bromide ions.

How the Calcium Bromide is Produced

When the calcium oxide is reacts with the bromine that has been strongly heated in the air and it gives the results of calcium bromide as the product and oxygen as the byproduct. It also crystallizes in an aqueous solution to exposed in the carbon dioxide rich atmosphere. The oxygen help out the bromide to bromine. The chemical reaction is given as follows.
