What is the pH of barium chloride? - Quora

Answer (1 of 2): Barium chloride — BaCl2 — dissolves in water and ionizes to form Ba2+(aq) ions and Cl- ions. Since Ba2+ and Cl- are the cation and anion of a strong base and a strong acid, they do not hydrolyze (react with water). Therefore, there are no additional H+ or OH- …

Common Uses of Barium - Owlcation

Barium is an interesting metal, with an interesting history, and an odd array of uses. While it is one of the most common elements found in the earth's crust, your odds of finding it in elemental form on a morning stroll are exactly zero. It is a highly reactive metal which oxidizes quickly in air, creating barium carbonate, and barium peroxide.
