The agar-water gel set-up used a petri-dish of agar-water gel with three wells on it. A drop of potassium permanganate (KMnO4) was put on one well‚ a drop of potassium dichromate (K2Cr2O7) was put on the other and a drop of methylene blue was put on the third well. Methylene blue which has the heaviest molecular weight of 374 g/mole occupied a small diameter of colored area which

an 80 year old mother of four. She developed pneumonia and checked in to Good Hope Hospital‚ Birmingham to be treated in the intensive care unit. While being treated for low serum potassium levels her nurse Mrs. Lisa Sparrow‚ RN entered an incorrect time frame on the infusion pump giving her a fatal amount of potassium chloride in one hour instead of over five hours. I will walk through this incident and illustrate the areas in which checkpoints that are set up for nurses should have been utilized

hydrated aluminum potassium sulfate salt in a sample of impure scrap aluminum from a common beverage can. The sample will be passed through a filter paper using a funnel‚ after being boiled on a hot plate in a fume hood and dissolved in a solution of potassium hydroxide to remove the impurities. By adding an excess of sulfuric acid and cooling the solution in an ice bath‚ the technique of vacuum filtration using a Buchner funnel will be employed‚ crystals of the hydrated aluminum potassium sulfate salt

obvious. Instead‚ back titration will be employed. The titration of a reducing agent with iodine to produce iodide ion is referred to as an iodometric titration. Iodine is generate by adding a weighed amount of standard potassium iodate (KIO3) to an excess of potassium iodide (KI) and then add adding strong dilute sulphuric acid (H2SO4) to produce iodine as shown below: (1) KIO3(aq) + 5KI(aq) + 3H2SO4(aq) → 3I2(aq) + 3H2O(l) + 3K2SO4(aq) The known excess of I2 generated by the reaction

as a heritable disease of the muscle‚ which is caused by a genetic defect. Some humans have also been known to carry a rare disease very similar to this‚ called Eulenberg ’s disease. HYPP causes muscle weakness or paralysis and is related to high potassium levels in the bloodstream. According to the Swedish National Board of Health and Welfare‚ "the cause of hyperkalemic periodic paralysis [in humans] is a change in a gene that regulates the production of a protein in the sodium ion channel of
