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.
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 chloride fluoride is an inorganic chemical compound of barium, chlorine, and fluorine. [1] Its chemical formula is BaClF. [2] [3] The compound naturally occurs as zhangpeishanite mineral of the matlockite group. [4] One of the deposits where the mineral is mined is Bayan Obo in China. [5]
Barium perchlorate can be prepared using many different reagents and methods. One method involves evaporating a solution containing barium chloride and an excess of perchloric acid. The dihydrate form is produced by recrystallizing and drying to a constant weight. Additional drying over sulfuric acid yields the monohydrate.
