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 ( 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 inside of the body).
Barium sulfate appears as white or yellowish odorless powder or small crystals. Mp: 1580°C (with decomposition). Density: 4.25 -4.5 g cm-3. Insoluble in water, dilute acids, alcohol.Soluble in hot concentrated sulfuric acid.Used as a weighting mud in oil-drilling, in …
Answer (1 of 2): if the mixture is just a mechanical mixture of the 2 anhydrous salts without any other substance in the system at a temperature near 25 degC, then nothing will happen. however, i'll assume that the writer was imprecise and was asking about an aqueous mixture at near 25 degC and ...
(iv) Barium sulfate (barium sulphate), a white precipitate, forms on mixing e.g. barium chloride solution and dilute sulfuric acid - but it can be any soluble barium salt solution mixed with a solution of any soluble sulfate salt solution. barium chloride + sulfuric acid ==> barium sulfate + hydrochloric acid
10.3 Precipitation of Barium Sulfate – Procedure All work should be done in the hood! Safety Notes: Barium is a heavy metal and you should avoid contact with the barium solutions and precipitates as much as possible. If you splash some solution on your hands, wash them immediately. Be sure to dispose of the filtrate and solid properly.
Barium sulfate suspension, often simply called barium, is a contrast agent used during X-rays. Specifically it is used to improve visualization of the gastrointestinal tract (esophagus, stomach, intestines) on plain X-ray or computed tomography. It is taken by mouth or used rectally.. Side effects include constipation, diarrhea, appendicitis, and if inhaled inflammation of the lungs.
DESCRIPTION. LIQUID POLIBAR PLUS ® Barium Sulfate Suspension (105% w/v, 58% w/w) is a barium sulfate suspension for oral and rectal administration. Each 100 mL contains 105 g barium sulfate. Barium sulfate, due to its high molecular density is opaque to x-rays and, therefore, acts as a positive contrast agent for radiographic studies.

Barium sulfate products may occasionally intravasate into the venous drainage of the large bowel and enter the circulation as a "barium embolus" leading to potentially fatal complications which include systemic and pulmonary embolism, disseminated intravascular coagulation, septicemia and prolonged severe hypotension.

Barium sulfate, due to its high molecular density, is opaque to x-rays and, therefore, acts as a positive contrast agent for radiographic studies.
barium sulfate. This is a heterogeneous equilibrium, one which contains substances in more than one state. In a heterogeneous equilibrium, concentration terms for solids are left out of the expression. Solubility products for more complicated solids Here is the corresponding equilibrium for calcium phosphate, Ca3(PO4)2: Ca3(PO4)2(s) ⇌ 3Ca2+(aq)+2PO3−4(aq)(4) Below is the solubility product ...
The precipitation of barium sulfate from aqueous solutions of barium chloride and sodium sulfate was investigated experimentally in a continuous Y-Mixer to avoid any mixing influence. Initial supersaturation and the initial ratio R = c B a free 2+ / c S O 4, free 2 − of the free lattice ions after complete educt mixing were varied over a ...
I found barium sulfate for about $23 for 500 g. with shipping. The best mix according to the article is a 50/50 mix by weight. 500 g. converts to around 17.6 ounces. I'm not sure how much white paint weighs, but I suspect it wouldn't take very many fluid ounces to equal 17.6 ounces by weight. That would make the paint quite expensive and you ...
Barium sulfate is commonly used to prepare contrast media for videofluorograpy. The flow characteristics of thickened liquids formulated for oropharyngeal imaging are known to be greatly affected by the addition of barium. In this study, thickened barium liquids were prepared by mixing a …
When barium chloride and sulfuric acid solutions are mixed, barium ions and sulfate ions exits in a same solution for a moment. Immediately, with the mixing you will see a white precipitate is formed. That white precipitate isbarium sulfate. As the other product, hydrochloric acid (HCl) is given. Balaced equation of BaCl 2 + H 2 SO 4
Barium sulfate comes as a powder to mix with water, a suspension (liquid), a paste, and a tablet. The powder-water mixture and suspension can be taken orally or can be administered as an enema (liquid instilled into the rectum), and the paste and tablet are taken orally. Barium sulfate is usually taken one or more times before an X-ray ...
Barium sulfate is mixed with warm water in a proportion of 2: 1 or 4: 1 and thoroughly mixed until a uniform consistency is obtained. Adult dose 300 ml, for children up to 100 ml. Barium gruel is injected through the mouth or probe directly into the stomach.

Barium will work better if your stomach and bowels are empty. It is important to drink plenty of liquids during and after the test. Barium sulfate may cause severe constipation. Barium sulfate is also available as an enema and given through the rectum. Before Using.
The scaling reaction depends on there being sufficient concentrations of sulfate ions in the injected seawater, and barium, strontium and/or calcium-divalent cations in the formation brine to generate sulfate scale; or on sufficient bicarbonate and calcium ions to allow the formation of carbonate should the physical conditions result in a change in equilibrium.

On mixing Barium chloride with Magnesium sulfate solution, a white precipitate of Barium sulfate is formed. This is also an example of "Double Displacement Reaction." This reaction is often used as a test for sulfate ions in a solution. Uses of Barium Sulfate. 1.
The barium sulfate suspension, while only 2% weight per volume, is thick, milky looking drink that can be best described as tasting like latex paint. This analogy is appropriate because the barium sulfate will taste different to everyone. The only constant is that no one, at least no sane person, has tasted barium sulfate and asked for more!
Imagine that the unknown solution contains aqueous ammonium sulfate, which is commonly used in fertilizer. For the precipitation of barium sulfate after mixing aqueous ammonium sulfate and barium chloride (the reactants), write the (1) balanced molecular equation, (2) the complete ionic equation, (3) the net ionic equation AND identify the spectator ions, if any.

Barium sulfate is used to identify the teeth from the diagnostic wax-up in a 20% BaSO4 solution. If a soft tissue (flapless surgery) template is to be made, teeth are ideally identified with a 20% BaSO 4 solution, and the base (soft tissue) uses a 10% mix. This allows for differentiation of the teeth from the soft tissue.
Barium sulfate is an insoluble material which, because of its density, provides a positive contrast during x-ray examination. Barium sulfate is an inert radiopaque material which is not absorbed or metabolized and is eliminated intact from the body in a …
