[9]: 2–3 Reactions with water and alcohols are also exothermic and release hydrogen gas: [9]: 3 Ba + 2 ROH → Ba(OR) 2 + H 2 ↑ (R is an alkyl group or a hydrogen atom) Barium reacts with ammonia to form the electride [Ba(NH 3) 6](e −) 2, which near room temperature gives the amide Ba(NH 2) 2. [11] The metal is readily attacked by acids.
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.
The Periodic Table of Videos has filmed at least one video for each of the 118 elements (from hydrogen to oganesson). [13] They have also filmed several videos that discuss molecules such as D 2 O (heavy water) [14] and sulfuric acid. [15] Also filmed are "Chem definitions" that provide an explanation to words that are used in chemistry.
In chemistry, a reactivity series (or reactivity series of elements) is an empirical, calculated, and structurally analytical progression [1] of a series of metals, arranged by their "reactivity" from highest to lowest.
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.
Carl Wilhelm Scheele (German:, Swedish: [ˈɧêːlɛ]; 9 December 1742 – 21 May 1786 [2]) was a German Swedish [3] pharmaceutical chemist.. Scheele discovered oxygen (although Joseph Priestley published his findings first), and identified molybdenum, tungsten, barium, nitrogen, and chlorine, among others.
Barium acetate is generally produced by the reaction of acetic acid with barium carbonate: [2] BaCO 3 + 2 CH 3 COOH → (CH 3 COO) 2 Ba + CO 2 + H 2 O. The reaction is performed in solution and the barium acetate crystalizes out at temperatures above 41 °C. Between 25 and 40 °C, the monohydrate version crystalizes. Alternatively, barium ...
Barium carbonate is the inorganic compound with the formula BaCO 3. Like most alkaline earth metal carbonates , it is a white salt that is poorly soluble in water. It occurs as the mineral known as witherite .
