Barium chloride is the inorganic compound with the formula BaCl2. It is a soluble barium compound, useful for the preparation of various barium compounds.
Barium chloride reacts with sulfates to precipitate barium sulfate. This reaction is used in identifying the sulfate species in a sample. This also works with oxalates or carbonates.
Barium chloride is a white solid, soluble in water and methanol, but insoluble in ethanol and alkanes.
Barium chloride can be purchased online.
A good method of obtaining barium chloride from pottery-grade barium carbonate can be found here.
- Sulfate test
- Make green flame
Barium chloride, like the other water-soluble barium salts, is highly toxic if ingested. A soluble sulfate salt, such as sodium sulfate or magnesium sulfate can be used as antidotes, as they convert the soluble barium ions to the insoluble barium sulfate, which is relatively non-toxic.
Barium chloride should be stored in closed bottles.
Barium chloride should be mixed with sodium sulfate or magnesium sulfate before disposal.
