Sodium

blocks voltage-gated sodium ion channels. Describe the structure of a sodium ion. A sodium ion is essentially a sodium atom which had been oxidized, losing one electron and gaining a positive charge. Thus, the atomic structure of a sodium ion is an atom with 11 protons in its nucleus, but only 10 electrons in its orbitals, thus explaining its positive charge. Atomic Structure. (2015).

addition, sodium chloride solution was added to one of the test tubes and sodium iodine to the other. After the two test tubes containing the solutions were thoroughly mixed, bromine water was added drop by drop, checking for any change during the addition of each drop of bromine water. Any changes in color or texture were recorded. The next two trials were conducted in the same manner, but with the following exceptions. The sodium halide salts used for trial two were sodium iodine and sodium bromine

1) The correct amount of sodium is important in the body because it helps control blood pressure and regulates the function of muscles and nerves (http://healthyeating.sfgate.com/actions-sodium-human-body-8362.html). Sodium attracts and holds water to help maintain the blood pressure, but if you consume to much sodium the body will hold on too much water which can increase your blood pressure (http://healthyeating.sfgate.com/actions-sodium-human-body-8362.html). Sodium comes from a variety of food

bleach. The bleaching agent present in the detergent is a chemical called sodium hypochlorite, which is the focus of our discussion in this lesson. !!!What is Sodium Hypochlorite? When our favorite articles of clothing get stained, and when we need to clean our bathrooms, we reach for our laundry detergent household cleaners that contain bleach. Bleach The main constituent of household bleach is a chemical called sodium hypochlorite. __Sodium hypochlorite__ in liquid form is greenish or yellowish

Kade McCorstin sodium MR.O May 10 ,2018 Word count: Sodium This element that is called Sodium has a very soft sort of silvery outer layer. Once sodium is cut the surface of the sodium will then air out into a dull kind of oxidized coating. Sodium is a very reactive chemical element that is found in the planet's crust. 2.6% of the earth's crust is sodium, and the reason that we can't find any sort or sodium on the ground is because sodium is reactive to any sort of the earth's moisture can and will

The sodium carbonate was added in this experiment is because it separates the hydroxyl group’s hydrogen atom from the oxygen on PABA. The O- on sodium carbonate attacks the hydrogen on the hydroxyl group of PABA, thus making the sodium carbonate a hydroxyl group. Meanwhile, the initial hydroxyl group on PABA becomes O-. This reaction makes the oxygen atom on PABA polar. The reason to make the oxygen on PABA polar is to make it dissolve in water, because water is polar, and polar likes polar; thus

create precisely two grams of precipitate from a reaction has been determined. 4 grams of water was added to the 2.94 grams of Calcium Chloride, and 10 grams of water was added to the 2.12 grams of Sodium Carbonate in an attempt to create two grams of precipitate. The final mass of the Calcium Chloride and Sodium Carbonate was 2.037 grams, resulting in a percent error of 1.85%. The class data was not collected, therefore a class average cannot be calculated; however a percent error of only 1.85% is extremely

Although that sodium is one

Title: The effect of Hydrochloric Acid volume with Sodium Thiosulphate on the reaction rate. Introduction: Research Question: How does changing the volume of Hydrochloric Acid on Sodium Thiosulphate effect the time taken for the ‘X’ Mark to dissapear? The rate of a chemical reaction is the time required for a given quantity of reactant to be changed to product. The unit of time may be seconds, minutes, hours, days or years. For a chemical reaction to occur it needs to have a collision, and it is

acetone biosensor was performed within the school grounds. Vanillin and sodium nitroprusside were used as the color-forming molecules for the detection of acetone. Varying concentrations of chemically-manufactured acetone solution were used in this experiment, which also acted as the control for the detection of acetone. Measurement was made using the UV-Vis spectrophotometer. The stock solutions were prepared using acetone, sodium nitroprusside and vanillin having 100 ppm as the fixed concentration
