Usage And Synthesis Description
Barium hydroxide is available as colourless or white crystals. It is odourless and soluble in water. It is stable under ordinary conditions of use and storage. It is incompatible with acids, oxidisers, and chlorinated rubber. Barium hydroxide is corrosive to metals such as zinc. Barium hydroxide is very alkaline and rapidly absorbs carbon dioxide from air, becoming completely insoluble in water. Barium hydroxide is used in analytical chemistry for the titration of weak acids. Barium hydroxide is used in organic synthesis as a strong base. Barium hydroxide decomposes to barium oxidee when heated to 800°C.
