Barium Hydroxide
Barium hydroxide is a chemical compound that can be made up of one atom of barium, two atoms of hydrogen and two atoms of oxygen. It has no odourless and looks like a white powder naturally. It is obtained through the dissolving in water. The barium hydroxide is so harmful when you inhaled it or swallowed it. It has more toxicity and more corrosiveness. The systematic IUPAC name is known as Barium hydroxide. The chemical or molecular formula of Barium hydroxide is Ba(OH)2. It is also known as barium dihydroxide or caustic baryta.
Structural Formula
This is the structural formula of the barium hydroxide:
Chemical Formula
The chemical formula or molecular formula is Ba(OH)2.
Preparation Method
The barium hydroxide can be prepared by the reaction of dissolving barium oxide in the water. The octahydrate is crystallized when it converts to the monohydrate at the heating in air. It has six water hydroxide ligands. These barium oxide is very useful to the manufacturing the chemicals in the industry. The chemical reaction is given as follows.
BaO + H2O → Ba(OH)2
