Barium

multipurpose strip in the urine sample for a certain amount of time. Then, cross-examine the color on the color table and the color the strip showed. For testing sulfate, the experimenter had to put 5.0 mL of urine in a test tube, add 5 drops of 10% barium chloride and .1 M of hydrochloric acid. To test the urine for chloride, 5 mL of urine also had to be put into a test tube and 3 drops of silver nitrate had to be added to it. Organic molecules presence was determined by observing the colors on…

The beginning of the lab contained a substantial amount of information detailing what chemical properties make up the structure of a salt hydrate. It provided essential knowledge proceeding to the successful completion of this lab such as the idea that hydrates are salt compounds which have formed weak bonds to water molecules that can easily be broken through the use of heat. With this information in mind, it was expected that a series of procedural guidelines following this information be used…

As I expected, each compound that we had tested showed different colors or at least different shades of it sometimes. Due to the different colors there some compound that were very easy to identify. Barium and Potassium were very easy to identify. Barium was a very distinct shade of green. It is very noticeable and easy to identify, but potassium is equally easy to identify thanks to its violet color. On the other hand, there were also compounds that were hard to identify.…

substance in a specific set are used to find the actual substances. The following sets of substances could have been assigned: Set 1 - Silver nitrate (AgNO3), Manganese(II) nitrate (Mn(NO3)2), Barium nitrate (Ba(NO3)2), Hydrochloric acid (HCl), Sodium Hydroxide (NaOH); Set 3 - Silver nitrate (AgNO3), Barium nitrate (Ba(NO3)2), Hydrochloric acid (HCl), Sulfuric acid (H2SO4), Sodium Hydroxide (NaOH); Set 4 - Silver nitrate (AgNO3), Lead (II) nitrate (Pb(NO3)2), Hydrochloric acid (HCl), Ammonia…

came into existence and why it is arranged the way it is. He also looks deeply into the history and concepts of some interesting elements. In chapter 15 called “An Element of Madness,” he goes into an explanation about selenium, manganese, palladium, barium, and unununium. Pathological science is considered madness because of how the theory or conception can not be really proven wrong, but at the same time it is delusional. The chapter is named the way it is because the elements that are…

Discussion The findings in this lab show that the melting point of Alum is 92.5 degrees Celsius. During the first trial a temperature of 91.0 degrees Celsius was recorded, but during the second trial a temperature of 93.0 degrees Celsius was found. Averaging the two temperatures gives a total around 92.0. The literature melting point of Alum is said to be 92.5 degrees Celsius and the data from similar studies, such as, Chemistry 103: Synthesis of Alum, together show that the results from the…

scans. Endoscopy. In this test the lining of the colon is examined with a flexible tube with a light and camera at the end. A biopsy. In this test a tissue sample is taken from your colon for examination. A barium enema. In this test a chalky fluid called barium is given as an enema. Then, X-rays of the bowel are taken. TREATMENT There is no cure for this condition, but the condition can be managed. Treatment depends on the child's age and the severity of the disease. It often…

a physical examine.He may detect enlarged lymph-nods, enlarged liver, increased fluid in abdominal, or abdominal lumps felt during rectal exam. upper gl series are x-rays of esophagus,stomach, and first part of intestine after you drink barium solution the barium autines the stomach on the x-ray, which helps doctors using special equipment , to find tumors also the doctor may use a small camera he may put it through gastroscopy and bioposy the test examines the esophagus and stomach using a…
