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]
The dihydrate is dehydrated by heating to 100 °C in air for one hour followed by 5.5 hours at 520 °C under argon. [3] If the presence of other anions is suspected, the dehydration may be effectuated by fusion under hydrogen chloride. [4] Radium chloride can also be prepared by heating radium bromide in a flow of dry hydrogen chloride gas. It ...
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 iodide is an inorganic compound with the formula BaI 2. The compound exists as an anhydrous and a hydrate (BaI 2 (H 2 O) 2), both of which are white solids. When heated, hydrated barium iodide converts to the anhydrous salt. The hydrated form is freely soluble in water, ethanol, and acetone.
