What is barium and its uses?

Uses and properties Barium is a soft, silvery metal that rapidly tarnishes in air and reacts with water. Uses. Barium is not an extensively used element. Most is used in drilling fluids for oil and gas wells. It is also used in paint and in glassmaking.

What are 5 uses of barium?

Uses of Barium

• Barium is often used for spark-plug electrodes and in vacuum tubes as a drying and oxygen-removing agent.
• Its compounds are used by oil and gas industries to make drilling mud.
• Barium compounds are also used to make paint, bricks, tiles, glass, and rubber.

Why is BaCl2?

Barium chloride is an inorganic compound with the formula BaCl2. It is one of the most common water-soluble salts of barium. Like most other barium salts, it is white, toxic, and imparts a yellow-green coloration to a flame….Barium chloride.

How is BaCl2 formed?

Formula and structure: The barium chloride chemical formula is BaCl2 and the molar mass is 208.23 g mol-1. This salt is formed by one barium cation (Ba2+) and one chlorine anion (Cl-). Barium salt also has a dihydrate form with a molar mass 244.26 g mol-1.

What are the properties and uses of barium chloride?

It is commonly used as a test for sulfate ion. In industry, Barium Chloride is mainly used in the purification of brine solution in caustic chlorine plants and also in the manufacture of heat treatment salts, case hardening of steel, in the manufacture of pigments, and in the manufacture of other barium salts.

What are uses for lanthanum?

5Uses. Lanthanum is one of the rare earth elements used to make carbon arc lights which are used in the motion picture industry for studio lighting and projector lights. Lanthanum also makes up about 25\% of Misch metal, a material that is used to make flints for lighters.

Is barium used in paint?

Two features give the newly-developed white paint its extreme whiteness. One is the high concentration of barium sulfate, which is also used to make photo paper and cosmetics white. The second feature is that the barium sulfate particles are all different sizes in the paint.

What is the use of barium sulphate?

Barium sulfate is used to help doctors examine the esophagus (tube that connects the mouth and stomach), stomach, and intestine using x-rays or computed tomography (CAT scan, CT scan; a type of body scan that uses a computer to put together x-ray images to create cross-sectional or three dimensional pictures of the …

How do you identify barium chloride?

Sulfate ions in solution, SO 4 2 -, are detected using barium chloride solution. The test solution is acidified using a few drops of dilute hydrochloric acid, and then a few drops of barium chloride solution are added. A white precipitate of barium sulfate forms if sulfate ions are present.

Why is barium chloride used in fireworks?

It’s all about chemistry. Elements such as sodium nitrate will yield a yellow color. Copper chloride gives you blue fireworks. Barium chloride gives you green fireworks. These metal salts are packed into fireworks and then sent into the air where they explode and illuminate in their according colors.

What is barium chloride charge?

Barium chloride is an ionic compound composed of one barium cation and two chlorine anions. In this case, chlorine will want to have a −1 oxidation state due to its high electronegativity. There are two chlorine atoms, so the total oxidation state will be −1⋅2=−2 .

What are the uses of europium?

Europium is excellent at absorbing neutrons, making it valuable in control rods for nuclear reactors. Europium-doped plastic has been used as a laser material. It is also used in making thin super-conducting alloys.

What are the uses of barium chloride?

Barium Chloride is used as a raw material to produce barium salt. It is used in chlorine-alkali industries. Used in the manufacturing of rubber. It is widely used in oil refining. It is used in the papermaking industry. It is used in the hardening of steel.

What is the use of BaCl2 in rubber?

Uses of Barium Chloride (BaCl 2) Barium Chloride is used as a raw material to produce barium salt. It is used in chlorine-alkali industries. Used in the manufacturing of rubber.

What is the function of BaCl2?

Barium chloride (BaCl2) is cheap and soluble salt and so finds wide spread of function and uses. It is used as a chemical indicator for sulphate . It is used as raw material for producing barium salts.

Is BaCl2 soluble or insoluble in water?

Properties of Barium Chloride – BaCl 2 Barium chloride is quite soluble in water (as is the case with most ionic salts). It is known to dissociate into barium cations and chloride anions in its dissolved state. At a temperature of 20 oC, the solubility of barium chloride in water is roughly equal to 358 grams per litre.
