Barium is a soft, reactive, silvery-white, alkaline earth metal, somewhat resembling metallic calcium. Sir Humphry Davy first isolated it in The periodic table lists the alkaline earth metals from lightest to heaviest as beryllium, magnesium, calcium, strontium and barium. You can prepare it through double-displacement reactions such as the following:. Barium sulfate is remarkably stable and cannot be converted to something else using this sort of reaction.
Barium sulfate is white to pale yellow in color and is nonflammable, with a melting point of 1, degrees Celsius. It possesses an unusually high specific gravity of 4. Particles of barium sulfate are considered inert, so in cases of inhalation, it is labeled as a "nuisance dust. This makes it useful for quick flow-through catalytic reactions employing partially deactivated palladium called Lindlar's catalyst.
In general, barium salts are quite water-soluble. Since barium sulfate does not dissolve in water, no such ions form. Since the barium atom is large and heavy, it absorbs X-rays quite well.
Since the sulfate also possesses no toxicity, it is used as a radio-opaque or radio-contrast agent in gastrointestinal testing. A barium "milkshake" or "meal," a drinkable aqueous suspension, is consumed gradually, beginning 90 minutes to two hours before testing begins.
Side effects may include nausea, diarrhea and headache. Barium sulfate is used in oil-drilling mud, textiles, pigments, photographic papers, ceramics and glasses, artificial ivory, and battery plate pastes. Although definitely stable and safe for ordinary use, barium sulfate can react explosively if mixed with aluminum and heated.Optical mouse sensor raspberry pi
In a fire, barium sulfate generates toxic sulfur oxides. If improperly made, such as in a famous incident in Brazil, it can cause death. This incident stemmed from illegal preparation, resulting in contamination by the water-soluble carbonate.

He has written technical articles since About the Author. Photo Credits. Copyright Leaf Group Ltd.Barium sulfate suspensionoften simply called bariumis a contrast agent used during X-rays.
Side effects include constipationdiarrheaappendicitisand if inhaled inflammation of the lungs. Barium sulfate has been known since the Middle Ages.Hackerrank questions
Barium sulfate suspensions are provided by a radiologist or radiographer in advance of, or during a CT scan or fluoroscopic study to allow for better visualization of the gastrointestinal tractsuch as in upper or lower gastrointestinal series. In upper gastrointestinal seriesthe patient is instructed to take nothing by mouthwhich means to abstain from eating and drinking fastingwith the exception of drinking the barium sulfate suspension.
The amount of time for this fast may vary, depending on the instructions given by the imaging facility and the area of the body to be scanned, but generally lasts for several hours prior to the scan.
The patient generally skips one meal, along with abstaining from all liquids, clear or otherwise, during this time. For a Barium Swallow or Dysphagiagram the barium is consumed after the study begins to discern if the patient has difficulties swallowing or masticating. Consumption is paced, beginning two hours before the scan is to occur, with levels marked on the provided container indicating how much is to be consumed between each of the two hours prior to the test.
A small portion of the suspension is reserved for the minutes just before the test, to ensure that as much of the gastrointestinal tract as possible is coated. After the scan is complete, the patient is encouraged to eat and drink normally, with special attention to plenty of fluids. The barium sulfate is excreted through defecationso extra fluid intake helps prevent constipationwhich is a possible side effect see Johns Hopkins Medicine Health Library for an example of a possible patient education instruction sheet.
Some patients with allergies or sensitive stomachs may choose to discuss alternatives to the barium sulfate suspension with their radiologist, but most patients find the common side effects more of an annoyance than a serious problem.
Among the possible side effects, listed on MedlinePlus are nausea and diarrheawhich may begin as soon as 15 minutes after consumption begins and may persist through the day after the test is completed. Other side effects may include a feeling of weakness, pale skin, ringing in the ears, constipation, and vomiting.
Patients may be strongly encouraged to avoid vomiting, as expelling a substantial quantity of the suspension may void its effect on the CT scan and produce unusable results, requiring a retest. As with most medications, if any severe side effects are experienced the patient is encouraged to contact their doctor or local poison control center immediately.
Oral barium sulfate suspensions are sometimes described as having the consistency of a very thick glass of milk, or a very thin milkshake. Roscoe Miller, in his article, "Flavoring Barium Sulfate", noted that taste thresholds vary per person,  and patient toleration of the medicine also varies. The suspension is typically homogeneous, smooth, and white in color. If the test requires the suspension to travel quickly through upper gastrointestinal tract it may be given chilled.
Many preparations of barium sulfate have added flavors to make them easier to tolerate. In general, the flavor is considered unpleasant, and is dependent on the exact makeup of the drink.
Because of the ease of the actual test, the paced two-hour consumption of the barium sulfate suspension is often considered the worst part of a CT scan. From Wikipedia, the free encyclopedia. Barium sulfate suspension 3D model of barium sulfate.

Barium sulfate is in a class of medications called radiopaque contrast media. It works by coating the esophagus, stomach, or intestine with a material that is not absorbed into the body so that diseased or damaged areas can be clearly seen by x-ray examination or CT scan.
Barium sulfate comes as a powder to be mixed with water, a suspension liquida paste, and a tablet. The powder and water mixture and the suspension may be taken by mouth or may be given as an enema liquid that is instilled into the rectumand the paste and tablet are taken by mouth. Barium sulfate is usually taken one or more times before an x-ray examination or CT scan. If you are using a barium sulfate enema, the enema will be administered by medical staff at the testing center.
If you are taking barium sulfate at home, take it exactly as directed. Do not take more or less of it or take it more often or at different times than directed. Shake the liquid well before each use to mix the medication evenly.
If you are given a powder to mix with water and take at home, be sure that you are also given directions for mixing and that you understand these directions. Ask your doctor or the staff at the testing center if you have any questions about mixing your medication. You will be given specific directions to follow before and after your test. You may also be told to use laxatives to clear the barium sulfate from your body after your test. Be sure that you understand these directions and follow them carefully.
Ask your doctor or the staff at the testing center if you are not given directions or if you have any questions about the directions you are given.
