    SODIUM gSodium is a chemical element with the symbol Na (from Latin: natrium) and atomic number 11. It is a soft‚ silver-white‚ highly reactive metal and is a member of the alkali metals; its only stable isotope is 23Na. The free metal does not occur in nature‚ but instead must be prepared from its compounds; it was first isolated by Humphry Davy in 1807 by the electrolysis of sodium hydroxide. Sodium is the sixth most abundant element in the Earth’s crust‚ and exists in numerous minerals such

  • Sodium Chloride

    Sodium chloride‚ also known as salt‚ common salt‚ table salt‚ or halite‚ is an ionic compound with the formula NaCl. Sodium chloride is the salt most responsible for the salinity of the ocean and of the extracellular fluid of many multicellular organisms. As the major ingredient in edible salt‚ it is commonly used as a condiment and food preservative. [edit] Properties Thermal conductivity of pure NaCl as a function of temperature has a maximum of 2.03 W/(cm K) at 8 K and decreases to 0.069 at 314

  • Periodic Table and Sodium

    Sodium‚ one of many elements in the periodic table is being used in everyday life‚ it is also an essential element within your body. It is just another element‚ but one of the differences is that this element is something that most people consume every day. Sodium has played an important role in everyday life because of its uses in medicine‚ industry‚ and agriculture(Shriver). Sodium was discovered in 1807 by a man named Sir Humphrey Davy. He was well known for his discoveries of most alkali metals

  • sodium hydroxide

    Sodium hydroxide‚ also known as caustic soda‚[2][3] or lye‚ is an inorganic compound with the chemical formula NaOH (also written as NaHO). It is a white solid‚ and is a highly caustic metallic base and alkali salt. It is available in pellets‚ flakes‚ granules‚ and as a 50% saturated solution.[citation needed] Sodium hydroxide is soluble in water‚ ethanol and methanol. This alkali is deliquescent and readily absorbs moisture and carbon dioxide in air. Sodium hydroxide is used in many industries

  • Sodium Chloride Experiment

    Making Sodium Chloride Equipment: Method: 1. Firstly‚ safety measures were taken by putting on laboratory coats‚ wearing safety goggles and tying long hair back. This was to protect clothing‚ eyes and to avoid burning as the experiment included dealing with open flames. 2. The equipment needed (as shown and labelled in picture A) was collected. 3. Using a measuring cylinder for each‚ to be exact with measurements‚ we measured out 10cm³ of HCl and 10cm³

  • Sodium Bicarbonate and Boxing

    KNES 470 Dr Rubin 4-18-12 Sodium Bicarbonate and Boxing Performance Boxing is a sport which relies on anaerobic power since it contains short-duration and high intensity work. A typical boxing match today consists of 3 minute rounds with a 1 minute seated recovery rest. When an athlete performs exercise at maximal level for more than 30 seconds‚ most of the energy comes from anaerobic glycolysis. During this process‚ lactic acid is produced which causes a decrease in pH levels within the muscle

  • Sodium Chloride Lab

    In the experiment‚ we tested a sodium chloride solution. Along with the tested solution‚ control groups (water and sodium phosphate) were used to be help understand whether or not NaCl was a buffer. Water was the negative control group and sodium phosphate was the positive control group. If NaCl was a buffer than the pH would be stabled as the sodium phosphate buffer. If NaCl was not a buffer than the pH would fluctuate like the negative control‚ water. During the first trial and prior to the drops

  • Standardization of Sodium Hydroxide

    12-STANDARDIZATION OF SODIUM HYDROXIDE Standard solutions for titrations are especially pure mixtures with exactly known concentrations. Primary standards are very pure solids. They have the advantage that they can be weighed (the analytical balance is normally the most accurate instrument in the laboratory) and they are stable under laboratory conditions. In this experiment‚ the primary standard is oxalic acid dihydrate‚ H2C2O4 ( 2H2O. It will be used to standardize a solution of sodium hydroxide
