Barium Phosphate Formula – Structure, Properties, Uses, Sample Questions

Barium is a soft, silvery alkaline earth metal. It is the fifth element in group 2 of the periodic table. The symbol of barium is Ba and has an atomic weight of 137.327 g/mol. Baryte and Witherite are the most common minerals of barium. It is additionally utilized in paint and in glassmaking. Looseness of the bowels are indication of barium harm in people exposed to high levels of barium

Phosphate is a salt or an anion derived from phosphoric acid. It is also called orthophosphate. It is a chemical formula of PO₄^3-and molar mass of 94.9714 g/mol. In the human body, phosphate is one of the components of teeth and bones. Phosphate rock is processed to produce phosphorous and it is one of the three main nutrients, commonly used in fertilizers. It is also used in beauty care products and food. High levels of phosphate are a significant indication of kidney damage.

What is Barium Phosphate?

Barium phosphate is a colorless chemical found in minerals and rocks in the form of alforsite and jagowerite. It is also called barium diphosphate. Barium phosphate is an inorganic salt which a density of 3.63 g/ml. 

Barium phosphate is insoluble in water and it also had a slight odor of acetic acid. There are many industrial applications. Barium phosphate has many properties including a high thermal expansion coefficient and high melting point. It is harmful to people and can cause irritation to the eyes. It is also used as a part of pulsed lasers. 

Structure of Barium Phosphate?

Ba₃(PO₄)₂ is the chemical formula of Barium Phosphate. It consists of three cations of barium (Ba²⁺) and two anions of phosphate (PO₄^3-). It has a molecular weight of 295.27 g/mol. The chemical formula barium phosphate in hydrated forms is Ba₂(P₄O₁₂).5H₂O, Ba₃(P₃O₉)2.6H₂O.

Preparation of Barium Phosphate

• It can be prepared by salt barium chloride with sodium metaphosphate, it is precipitated and then filtered from the solution.

BaCl₂+ 2NaPO₃ → Ba (PO₃)₂+ 2NaCl

• When barium carbonate reacts with the metaphosphoric acid it forms barium phosphate.

BaCO₃ + 2HPO₃ → Ba (PO₃)₂ +CO₂ +H₂O

Physical Properties of Barium Phosphate

• It is a colorless solid usually in powder form.
• The melting point of barium phosphate is 1560˚C.
• It is insoluble in water and has a density of 3.63 g/ml.
• Barium phosphate has a slight odor of acetic acid.
• It is insoluble in acidic solutions.
• It has a molecular mass of 295.27 g/mol.

Chemical properties of Barium Phosphate

• In industry, it is obtained by the mixture of barium carbonate with an excess amount of phosphoric acid and then later precipitation of the final product with barium hydroxide:

BaCO₃ + 2H₃PO₄ → Ba(H₂PO₄)₂ + CO₂ + H₂O

Ba(H₂PO₄)₂ + 2Ba(OH)₂ → Ba₃(PO₄)₂ + 2H₂O

• Barium phosphate with an excess amount of phosphoric acid forms a water-soluble dihydrogen phosphate,

Ba₃(PO₄)₂ + 4H₃PO₄ → 3Ba(H₂PO₄)₂

Uses of Barium Phosphate

• It is used to produce a mixture of sodium and barium polyphosphate, the important components of hot glasses with special properties.
• It is also used as a component of pulsed lasers. 
• It is also used as a proton-conducting material in fuel sensors.
• It is non-flammable so it can be used in the glass industry because of its high thermal coefficient and high melting point.
• Barium metaphosphate is used in porcelains and
• It is used in enamels as a flame retardant.

Safety Measures for Barium Phosphate

It is harmful to people when inhaled or swallowed. They require immediate medical attention. It causes irritation to the eyes, skin, and mucous membrane. Proper precautions should be taken. One should properly maintain protective wear like a mask, gloves, and proper clothes while handling. Proper labeling and storage should be given indicating the chemical name and hazard. Should be kept away from children. It should not be easily accessible by other persons.

Sample Questions

Question 1: Is barium a metal or not?

Answer: 

Barium is a delicate, brilliant metal that quickly discolors in the air and responds with water. Barium is certainly not a broadly utilized component. Most is utilized in boring liquids for oil and gas wells. It is additionally utilized in paint and in glassmaking. Barium is never found free in nature since it responds with oxygen in the air, framing barium oxide (BaO), and with water, forming barium hydroxide (Ba(OH)₂) and hydrogen gas (H₂).

Question 2: For what reason is barium poisonous, is a radioactive?

Answer:

In spite of the fact that barium carbonate is generally insoluble in water, it is harmful to people since it is dissolvable in the gastrointestinal tract. The insoluble mixtures of barium (prominently sulfate) are insufficient sources of Ba²⁺ ions and are commonly nontoxic to people.

Barium isn’t radioactive. It functions as an X-beam contrast medium since it is radiopaque or radio obscure, that is to say, it blocks X-beams so the subsequent picture plainly shows in white the state of organs that contain it.

Question 3: What food sources contain barium and phosphate?

Answer:

A few food sources, for example, Brazil nuts, kelp, fish, and certain plants, may contain high measures of barium. How much barium is found in food and water generally isn’t sufficiently high to be a well-being concern. Phosphorus is found in high sums in protein food sources, for example, endlessly milk items and meat and choices, like beans, lentils, and nuts. Grains, particularly entire grains give phosphorus. Phosphorus is found in more modest sums in vegetables and fruits.

Question 4: What is phosphate and how could it be utilized?

Answer: 

Phosphate rock is processed to deliver phosphorous, which is one of the three fundamental supplements most regularly utilized in manures (the other two are nitrogen and potassium). is a non-metal that sits just beneath nitrogen in group 15 of the periodic table. Phosphate can likewise be transformed into phosphoric acid, which is utilized in everything from food and beauty care products to animal feed and gadgets.

The fundamental function of phosphorus is in the formation of bones and teeth. It assumes a significant part in how the body utilizes sugars and fats. It is additionally required for the body to make protein for the development, upkeep, and fix of cells and tissues. Codeine phosphate, Effervescent sodium phosphate, Oleandomycin phosphate, and Utp-glucose-1-phosphate uridylyltransferase are a few instances of phosphate.

Question 5: Is the barium swallow test safe?

Answer:

A barium swallow is a safe test. However, there are potential dangers. Your PCP ensures the advantages of having the test offset the potential dangers. A limited quantity of barium fluid can go into the aviation route when you drink it. the Side Effects of a Barium Swallow test include:

• Hypersensitive response or hypersensitivity might happen in individuals who are sensitive to the barium drink,
• Constipation might create,
• One may incidentally get barium into the windpipe. The clinical term for this is an aspiration.
