Barium

Almost all of the barium consumed commercially is obtained from barite, which is often highly impure. Barite is processed by carbothermal reduction (heating with coke) to give barium sulfide: BaSO4 + 4 C → BaS + 4 CO In contrast to barium sulfate, barium sulfide is soluble in water and readily converted to the oxide, carbonate, and halides. To produce highly pure barium sulfate, the sulfide or chloride is treated with sulfuric acid or sulfate salts: BaS + H2SO4 → BaSO4 + H2S Barium sulfate produced

I had the opportunity to observe a Modified Barium Swallow Study at Arkansas Children’s Hospital this semester. It was informative, interesting, and sparked left me researching unfamiliar terms as I left the study. I was surprised at how much I enjoyed this observation experience and I feel as though it is one of the most, if not the most, beneficial hands on experiences I have had thus far. The differences between pediatrics and geriatrics have been discussed, taught, and even viewed through video

ADMIN NO: 1027325 CLASS: DFST/FT/2B/21 � SYNOPSIS The objective of this experiment is to determine the amount of sulphate by gravimetric analysis. The amount of sulphate is determined quantitatively as barium sulphate, BaSO4, by gravimetric analysis. For the experiment, a dilute solution of barium chloride was slowly added to a hot unknown sulphate solution slightly acidified with concentrated HCl. The precipitate is then filtered off by suction filtration, washed with water and dried in the oven

Reem Tahomi Chemistry 227 November 5, 2017 Which Alkali Metal Carbonate Abstract: The purpose of this lab was determining which alkali metal carbonate composes a given unknown sample by using three different methods. These three methods of flame test, simple weight loss calculation, and gravimetric analysis method were used to identify the properties and the molar mass of the unknown given sample. After doing the previous tests, it was discovered that the metal was Na2CO3 (sodium carbonate), and

Everyone should know that a lower GI is a very common and important exam used to diagnose many colon conditions. A lower GI examination, also know as a barium enema, is an x-ray examination of the large intestine. The large intestine, or large bowel, consists of the entire colon, including the appendix, rectum, and sigmoid colon. This commonly performed test is essentially the predecessor to the more familiar colonoscopy. A lower GI is used worldwide to help diagnose fatal diseases and many other

Barium is a soft silver that is alkaline earth metal. Barium is never found in nature as a free element. The two of the most commonly natural occurring minerals of barium are as followed: barite, and witherite, they both very insoluble in water . Barium was soon identified as a new element back in 1774. Barium ended up not being reduced until 1808. Barium was beginning to be used as a “getter” for different vacuum tubes. Many barium compounds

In conclusion to the first portion of the experiment, which included the continuous heating and cooling of a 1.5-gram sample of barium chloride dihydrate, the litmus paper tested indicated that there was no release of acidic vapors during the separating of the water and compound bonds. In other words, the chemical equation BaCl2 + 2H2O (s)  BaCl2 + 2H2O (g), labeled as 5.3 in the original lab report, is best used to describe the transition which took place during this portion of the lab. The second

Barium Enema A barium enema is an X-ray test. It is used to check for problems in the colon or in the last part of the small bowel. The colon is also called the large intestine. For this test, a liquid called barium will be put into your colon. The liquid shows up well on X-rays. This makes it easier to see problems. The test can help find the cause of symptoms such as belly pain or blood in your poop (stools). BEFORE THE PROCEDURE • Follow instructions from your doctor about what you cannot

Section 401 Formal Lab Report 1 09/21/2017 Gravimetric Analysis of Sulfate Formal Lab Report Abstract:     Three measures of unknown sulfate salt was measured and placed into three beakers with water, Hydrochloric acid, and Barium Chloride. The solutions were heated until Barium Sulfate precipitated and the solutions were filtered through ashless filter papers to collect the precipitate. The filter papers were combusted until only the BaSO4 remained, and the precipitates were massed in crucibles. Using

Barium Swallow A barium swallow is an X-ray exam that is used to evaluate the area at the back of your throat (pharynx) and the tube that carries food and liquid from your mouth to your stomach (esophagus). For this exam, you will swallow a white chalky liquid called barium. X-rays are done while the barium passes through your pharynx and esophagus. The barium makes it easier for your health care provider to see possible problems in this area. A barium swallow may be done to check for various problems
