Baryte, barite or barytes (/ ˈ b ær aɪ t, ˈ b ɛər-/ BARR-eyet, BAIR-[7] or / b ə ˈ r aɪ t iː z / bə-RYTE-eez [8]) is a mineral consisting of barium sulfate (BaS O 4). [3] Baryte is generally white or colorless, and is the main source of the element barium.
Barium sulfide is the inorganic compound with the formula Ba S. BaS is the barium compound produced on the largest scale. [ 3 ] It is an important precursor to other barium compounds including barium carbonate and the pigment lithopone , ZnS/BaSO 4 . [ 4 ]
Like all soluble barium compounds, barium nitrate is toxic by ingestion or inhalation. [8] Solutions of sulfate salts such as Epsom salts or sodium sulfate may be given as first aid for barium poisoning, as they precipitate the barium as the insoluble (and non-toxic) barium sulfate. Inhalation may also cause irritation to the respiratory tract.
Going for the 3-peat. The Chiefs are certainly aware of what's in front of them Sunday.But the players said they've been able to keep the focus on the challenge in front of them every week.
The barium derivative is useful in the gravimetric analysis of sulfate: if one adds a solution of most barium salts, for instance barium chloride, to a solution containing sulfate ions, barium sulfate will precipitate out of solution as a whitish powder. This is a common laboratory test to determine if sulfate anions are present.
