Barium Compounds. Barium sulfate (BaSO 4), or barite, is the most common mineral abundant in barium. This mineral has a density of g/cm 3 and is extremely insoluble in water. Uses of barium sulfate include being a radiocontrast agent for X-ray imaging of the digestive system. Barium carbonate (BaCO 3) is also commonly used as a rat poison. Barium - chemical symbol Ba, atomic number 56 - is an chemical element in the group of alkaline earth metals. Online available information resources about the chemistry and physics of barium and the barium compounds.

Barium and barium compounds 1 FOREWORD Concise International Chemical Assessment Documents (CICADs) are the latest in a family of publications from the International Programme on Chemical Safety (IPCS) — a cooperative programme of the World Health Organization (WHO), the International Labour Organization (ILO), and the United Nations.
The highest concentrations of barium in the body are found in the bone; approximately 91% of the total body burden is in the bone (WHO, ). Bauer et al. () reported that barium accretion rates for whole skeleton, tibia, and incisors were - times greater than accretion rates for Size: KB.
The available animal data provide strong evidence that the most sensitive adverse effect of barium is renal toxicity. There are some reports of renal effects in case reports of individuals ingesting high doses of barium. Nephropathy has been observed in rats and mice following long-term oral exposure to barium.

Use of pure barium sulfate is, e.g., as a filler and extender and as a contrast agent in X‐ray diagnosis. Barium carbonates are mainly used to remove sulfate ion impurities and to introduce barium oxide into special fine glassware such as cathode tube Cited by: Despite the toxicity of its compounds, barium sulfate is a compound given to patients as a ‘barium meal’ to allow X-ray imaging of the digestive system.
This is possible because of the low solubility of barium sulfate – this stops the patient absorbing harmful amounts of barium as it passes through their body.
This section lists some binary compounds with halogens (known as halides), oxygen (known as oxides), hydrogen (known as hydrides), and some other compounds of barium. For each compound, a formal oxidation number for barium is given, but the usefulness of this number is limited for p.
Barium carbonate is the source of barium compounds. It is produced in an aqueous precipitation reaction from barium sulfide and sodium carbonate.
(Barium sulfide is a soluble compound obtained by heating the mineral barite, which is barium sulfate, with carbon.) What are the molecular equation and net ionic equation for the precipitation reaction. Barium bromide has the molecular formula of BaBr 2.
Like barium chloride, it is soluble in water but is toxic if ingested. BaBr 2 crystallizes in a PbCl 2 motif, as white orthorhombic crystals that are deliquescent. In aqueous solution, BaBr 2 behaves as a simple salt. Barium sulfide is separated from impurities by extraction with hot water and filtration.
It is obtained as an aqueous solution of 15–30% strength. The commercial product is 80% to 90% BaS. Barium sulfide may also be made by high temperature reduction of barium sulfate with methane.
Barium compounds are added to fireworks to impart a green color. Barium sulfate is used as an insoluble additive to oil well drilling fluid, as well as in a purer form, as X-ray radiocontrast agents for imaging the human gastrointestinal tract.
The soluble barium ion and soluble compounds are poisonous, and have been used as rodenticidesPronunciation: /ˈbɛəriəm/ (BAIR-ee-əm). Get this from a library.

Represented by the symbol ‘Ba’, Barium is a group 2 element in the periodic table with atomic number Barium is a dense alkaline earth metal that occurs naturally in ore deposits and makes up % of the Earth’s crust (Genter ).
