[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 azide can be used to make azides of magnesium, sodium, potassium, lithium, rubidium and zinc with their respective sulfates. [4] Ba(N 3) 2 + Li 2 SO 4 → 2 LiN 3 + BaSO 4. It can also be used as a source for high purity nitrogen by heating: Ba(N 3) 2 → Ba + 3 N 2. This reaction liberates metallic barium, which is used as a getter in ...
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.
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.
Barium sulfate (or sulphate) is the inorganic compound with the chemical formula Ba SO 4. It is a white crystalline solid that is odorless and insoluble in water. It occurs in nature as the mineral barite, which is the main commercial source of barium and materials prepared from it. Its opaque white appearance and its high density are exploited ...
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 ...
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.
Barium titanate (BTO) is an inorganic compound with chemical formula BaTiO 3. It is the barium salt of metatitanic acid. Barium titanate appears white as a powder and is transparent when prepared as large crystals. It is a ferroelectric, pyroelectric, and piezoelectric ceramic material that exhibits the photorefractive effect.
