    Hydrochloride is a toxic acid when ingested or inhaled and is corrosive to skin and eyes and is best to avoided contact with body tissue. Strontium and barium are compounds that if ingested are highly toxic. Potassium iodate solution is moderate toxic but is a stronger irritant except water which in this case has no safety issues in relation to this lab. The element’s being used in this lab are aluminum, calcium and magnesium. What was needed was 4 pieces of each chemical and place in a 24 well reaction plate with calcium in column A magnesium in column b and aluminum in column c of the plate the place 20 drops of water to each well. With h20 in calcium, magnesium and aluminum we were to observe in the row for a reaction h20 has on the element in each well with a ph. test. The same was used but instead of water row b was used with HCI and row C was CACL2 and lastly row D was with BACL2 with the same metals just instead of h20 with those element with HCI etc. with 20 drops into each according well across row b, c and d. As for part B of the lab it was the three metals but with mg chlorine and calcium chlorine and strontium chlorine and barium chloride and an unknown chemical into the wells and then add sodium choline through a1 to a5 and b1-b5 sodium sulfate and lastly in row c potassium iodate.once data is collected the unknown well be able to be identified.…

    the patient preparation. CT colonography as well as barium enema require bowel preparation, the bowel need to be free from any faeces as its presence can mimic pathology and impair diagnosis. CT colonography offers cross sectional images and allows three dimensional reconstruction. This feature results in CT colonography to be known as virtual colonoscopy. The examination encompasses the uses of contrast and insufflation of the colon. Optimum bowel distension allows the visualisation of colonic…

    In the half-life of barium-137m graph, the results tended to lose activity as time progresses, indicating that barium-137m was undergoing a decay process. Initially, barium-137m had an activity of 4264 CPM (5 seconds in). After approximately five minutes, the activity had dropped to 1092 CPM, and after 10 minutes, the activity had dropped to 318 CPM. The radical changes between 4264 CPM and 1092 CPM compared to the changes from 1092 CPM to 318 CPM indicated exponentially decreasing activity.…

    Modified Barium Swallow A modified barium swallow, also referred to as a swallowing study, is an X-ray exam that is used to help find the cause of swallowing problems. For this exam, you will eat or drink various forms of food that are mixed with a white chalky substance called barium. While you are eating these foods, X-ray images are used to view the areas of your body that are involved in the process of chewing and swallowing. The barium mixed with the foods makes it easier for your health…

    is a method used to determine the mass or concentration of a substance by measuring a change in mass. To determine the concentration of the sulfate, the precipitation of Barium sulfate is done first by adding the sulfate solution with hydrochloric acid, then heating while stirring it. Next is the washing and filtration of the Barium Sulfate precipitate, using a vacuum pump and a crucible. Lastly, is the drying and weighing of the precipitate by heating the crucible in the oven and cooling it in…

    This experiments goal was to successfully produce ZnI2 by using Zinc Sulfate (Heptahydrate) and Barium Iodide Dehydrate, which Jessica and I did with acceptable success. The definition of acceptable success for this experiment is measured by how close our percent yield was close to the ranges provided (0-2% being considered excellent precision and etc). Our percent yield was 92 % meaning that it was an acceptable, but not exactly as close to what we wanted it to be. In order to try and figure…

    fourteen occurring reactions were precipitates. A precipitate means that a solid substance was formed or a substance that is not aqueous was formed. The reactions that did not form a precipitate were DNR, which means that they did not react. At station one barium chloride and potassium nitrate did not react but barium chloride and silver nitrate reacted to form barium nitrate and silver chloride. The precipitate at station one was silver chloride. Both reactions at station two did not react.…

    was confirmed in Part A and barium in Part B. In Part C, different colored flames of metal species were observed using cation flame tests. Formula unit, total ionic, and net ionic equations were then composed for the identified cations. If the experiment were to be repeated, step 13 could be ommitted as barium was already confirmed in step 12 with the formation of yellow percipitate barium chromate, and calcium was not confirmed with step 14 when a white percipitate calcium oxalate was not…

    In this experiment, qualitative analysis was used to identify two cations. Lead was identified in Part A, barium was identified in Part B and different flame colors were observed with various metal chloride solutions in Part C. Formula unit, total ionic, and net ionic equations were written for the confirmation reactions for both lead and barium. If this experiment was repeated, barium could be confirmed by the yellow precipitate BaCrO4 after confirming that the solution was clear and any…
