Barium chloride is an inorganic compound with the formula Ba Cl 2. It is one of the most common water-soluble salts of barium . Like most other water-soluble barium salts, it is a white powder, highly toxic, and imparts a yellow-green coloration to a flame.

A 0.5 McFarland standard is prepared by mixing 0.05 mL of 1.175% barium chloride dihydrate (BaCl 2 •2H 2 O), with 9.95 mL of 1% sulfuric acid (H 2 SO 4). [ 1 ] Now there are McFarland standards prepared from suspensions of latex particles, which lengthens the shelf life and stability of the suspensions.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

Barium chlorate, Ba(ClO 3) 2, is the barium salt of chloric acid. It is a white crystalline solid, and like all soluble barium compounds, irritant and toxic. It is sometimes used in pyrotechnics to produce a green colour. It also finds use in the production of chloric acid.
Barium hypochlorite is a chemical compound with the chemical formula Ba(O Cl) 2 (also written as Ba(ClO) 2). It is the barium salt of hypochlorous acid . It consists of barium cations Ba 2+ and hypochlorite anions − OCl .
Barium bromide can be prepared by treating barium sulfide or barium carbonate with hydrobromic acid: BaS + 2 HBr → BaBr 2 + H 2 S BaCO 3 + 2 HBr → BaBr 2 + CO 2 + H 2 O. Barium bromide crystallizes from concentrated aqueous solution in its dihydrate, BaBr 2 ·2H 2 O. Heating this dihydrate to 120 °C gives the anhydrous salt. [6]
