What is the purpose of nickel bromide?
The inorganic compounds having the chemical formula NiBr2(H2O)x are known as nickel(II) bromide. For the anhydrous substance, x can be 0; for the three known hydrate forms, x can be 2, 3, or 6. The anhydrous substance is a yellow-brown solid that dissolves in water to form a blue-green hexahydrate.
The structure of nickel bromides changes depending on the degree of hydration. The nickel(II) ion has an octahedral molecular geometry in all of these circumstances. Similar formations are seen in nickel bromide aqueous solutions.
