BARIUM CARBONATE Meaning and
Definition
-
Barium carbonate is an inorganic chemical compound with the formula BaCO3. It is a white, odorless powder that is insoluble in water and alcohol. The mineral form of barium carbonate is known as witherite.
In terms of its chemical composition, it consists of one barium (Ba) cation bonded to a carbonate (CO3) anion, which is a polyatomic ion composed of one carbon atom and three oxygen atoms. This chemical arrangement results in a salt-like compound.
Barium carbonate is primarily used in the production of various barium compounds, such as pigments, glass, ceramics, and pyrotechnics. It has also found applications in other industries, including the manufacturing of specialty glass, optical glasses, and television tubes. Additionally, it acts as a flux in the production of certain types of cement.
One of the noteworthy properties of barium carbonate is its ability to absorb X-rays. This characteristic makes it valuable in medical imaging studies, particularly as a contrast agent in radiographic exams of the gastrointestinal tract. Barium carbonate is ingested by patients in the form of a suspension, allowing for clear visualization of the esophagus, stomach, and intestines through X-ray imaging.
Due to its toxicity, barium carbonate should be handled with care. Exposure to this compound can lead to health issues such as gastrointestinal disturbances, muscle weakness, and cardiovascular problems. Therefore, appropriate safety precautions should be taken when working with or near barium carbonate in order to minimize any potential risks.
Etymology of BARIUM CARBONATE
The word "barium" originates from the Greek word "barys", which means "heavy". This is because barium is a heavy metal element with the atomic number 56. The term "carbonate" comes from the Latin word "carbonatus", which refers to a salt or ester of carbonic acid.
