Mô tả
Nickel(II) bromide, NiBr2, is the nickel salt of hydrobromic acid. It can be made by reacting nickel, nickel(II) oxide, nickel(II) carbonate, or nickel(II) hydroxide with hydrobromic acid. It can also be made by reacting nickel with bromine. It is a weak reducing agent.
It is yellow-brown, rhombohedral, hygroscopic, and is soluble in water and in ethanol. It dissolves in water to make a blue-green solution typical of soluble nickel(II) compounds. It can be used as a source of the bromide ion. It reacts with bases to make nickel(II) hydroxide.
Nickel(II) bromide, like most nickel compounds, is toxic and a suspected carcinogen. It can cause contact dermatitis in skin. The bromide ion is also mildly toxic.
