Barium :: essays research papers

atomic number 56 is a soft, heavy, silver-colored surface element. This element does not have very many uses outside of the laboratory, exactly it combines easily with other chemicals to form compounds utilize for important industrial uses. For example, Barium carbonate is used in the manufacture of ceramics and special glass, and alike to be sick certain chemical solutions. It is also an ingredient in clay slurries, also known as water muds, used in drilling anoint wells. Barium titanate is used in sonar celebrateors and other electrical equipment. At low doses, atomic number 56 acts as a muscle stimulant and at higher doses affects the nervous system eventually leading to paralysis. Acute and subchronic vocal doses of atomic number 56 cause vomiting and diarrhea, followed by decreased heart run and elevated blood pressure. Higher doses result in cardiac irregularities, weakness, tremors, anxiety, and dyspnea. A drop in serum potassium may account for whatever of the s ymptoms. Death can occur from cardiac and respiratory failure. Acute doses slightly 0.8 grams can be fatal to humans. Barium nitrate makes signal flares fire with a green flame. Barium ferrite is used to make magnets. Barium sulfate is an extremely insoluble barium compound that is not poisonous. Doctors use it in X-ray examinations of a patients digestive system. The barium sulfate absorbs X rays to memorialize an outline of the intestines on the developed film. A barium enema is performed to show the walls of the colon. During the procedure, a well lubricated enema tube is inserted gently into the rectum. The barium is then allowed to flow into the colon. The flow of the barium is monitored by the health guard provider on an X-ray fluoroscope screen. The test is used to detect colon cancer. The barium enema may also be used to diagnose and evaluate the extent of inflammatory bowel diseases. Barium sulfate and zinc sulfide form lithopone, a white coloring study for paint. Bar ium is never constitute in a pure rural area because it combines so easily with other elements. Pure barium is obtained by transitory an electric current through a fused barium compound, much(prenominal) as barium chloride. A piece of barium metal cursorily reacts with oxygen and water vapor in the air to form barium oxide. It must be stored under kerosene to keep it pure. Barium is found most often as barium sulfate in the mineral barite. The chemical symbol for barium is Ba.
