Barium chloride is the inorganic compound with the formula BaCl2. It is a soluble barium compound, useful for the preparation of various barium compounds.
Contents
Properties
Chemical
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.
Physical
Barium chloride is a white solid, soluble in water and methanol, but insoluble in ethanol and alkanes.
Availability
Barium chloride can be purchased online.
Preparation
Can be prepared by reacting barium carbonate with hydrochloric acid. The solution is concentrated by boiling it and is then left to cool, which causes the barium chloride to crystallize.
A good method of obtaining barium chloride from pottery-grade barium carbonate can be found here.
Projects
- Sulfate test
- Make green flame
- Barium chlorate synthesis
Handling
Safety
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.
Storage
Barium chloride should be stored in closed bottles.
Disposal
Barium chloride should be mixed with sodium sulfate or magnesium sulfate before disposal.
