Barium chloride is a chemical substance. It is among the most important salts of barium. It is soluble in water. It is a poison. When it is heated, it gives a yellow or green color to the flame. It is hygroscopic, meaning that it attracts water from the air. It is mainly used to purify brine but applications include fireworks.
