Sodium

when I mixed solid sodium carbonate with hydrochloric acid, copper (II) sulphate solution with liquid sodium carbonate, and during the end of the change when I applied heat to sugar. The test of mixing sodium carbonate with hydrochloric acid was a chemical change because of a creation of gas and the state of the sodium carbonate changing during the process, meaning a chemical reaction must’ve took place. Afterwards, the examination of mixing copper sulphate solution with sodium carbonate was…

Introduction Almost 100% of Americans consume more than the amount of sodium recommended by the American Heart Association, with approximately 60% of Americans consuming more than double the recommended value (Whelton). Sodium consumption is a concern because it is the direct cause of hypertension, which leads to many of the top preventable diseases of the circulatory system (Schieb). In 2010 approximately 200,000 people in the U.S. died from hypertensive disorders including heart disease,…

effects on the life you live. Sodium intake is a major problem the world faces, especially in the United States. Restaurants, fast food establishments, and processed food companies add salt to most of their dishes or products to add taste and give it a longer shelf life. When tracking my food intake this week, I realized I am apart of the majority that consumes too much sodium in my diet. Convenient foods that take little to no time too prepare that are loaded with sodium and other chemicals…

The different chemicals that were used in this experiment were Pilocarpine, Atropine Sulfate, Epinephrine, Digitals, Potassium, Sodium, and calcium ion concertation. Pilocarpine stimulates the effect of parasympathetic nerve stimulation by enhancing acetylcholine release. Atropine Sulfate is a drug that blocks the effect of the neurotransmitter acetylcholine which is liberated by the parasympathetic nerve endings. Cardiac muscle and skeletal muscle are both different in functionally and in fine…

Discussion The results of this experiment for the hypotonic treatment group did support the tested hypothesis that urine production rate should increase, while salt concentration and specific gravity of urine should decrease for this group. For the isotonic treatment group, the tested hypothesis was supported in that the specific gravity and salt concentration went up slightly, but was not supported in that the the urine production rate did not greatly increase over time. The findings for the…

threshold. In order to reach this threshold, a cell must depolarize. Typically, cells depolarize with the opening of voltage-gated sodium channels. During the rising phase of the action potential, these channels allow positive sodium ions to flow into the cell in what is called the depolarization phase. The flow of these ions into the cell is often referred to as the sodium current. Once the cell is depolarized, voltage-gated potassium channels are signaled to open, allowing potassium to flow…

Determination of Isoprenaline Hydrochloride Concentration Using Ultra Violet/ Visible Spectroscopy and Quantification of Sodium and Potassium Using Flame Spectroscopy Introduction In UV/VIS (ultraviolet-visible light) spectroscopy, light absorption as a function of various wavelengths gives data about electronic transitions within a solution [1]. The electronic transitions involve exciting an electron from one principle quantum state to another by the absorption of energy [2]. A change in…

What I have found about this experiment is some really interesting ideas and other ways to the experiment. Some other people use Sodium or other words, for Sodium on the periodic table this chemical is called “Na” other people use that to make the Elephant Toothpaste. The call it Elephant Toothpaste because it’s supposed to look like toothpaste and since it's so big and it looks like toothpaste so the first thing people thought of was Elephant Toothpaste. Is that it was so deadly and that it…

electrolysis of (KOH). The scientist used the same method to isolate sodium. KCI is the mineral that potassium can be obtained from. Caustic potash is a vital source of potassium that can be obtained in Germany, New Mexico, California, and Utah. Potassium is classified as a soft, waxy metal. If it is combined with oxygen it forms potassium superoxide and with water to form potassium hydroxide. If potassium is formed with sodium it can be used as a medium heat transfer. Davy’s experiments led him…
