Potassium's symbol is K which comes from the word kalium which comes from the Latinized version of the Arabic word for potash.
C. Potassium's atomic weight is 39.098.
D. Potassium is extremely soft metallic element that can be cut easily with a knife.
E. Potassium is found in nature in large quantities, ranking 8th in abundance in the earth's crust. .
Who discovered Potassium?.
A. Sir Humphry Davy believed a strong electrical current might be able to overcome forces binding compounds together, and lead to the isolation of new elements.
B. In 1807 he experimented caustic potash (Potassium Hydroxide, KOH) .
C. He fired a small piece of KOH in a furnace and placed it on a platinum plate. He connected the plate to the negative terminal of an large battery made of 250 stacked cells made of 6x4 copper and zinc plates. .
D. The positive terminal was connected to a platinum wire. The results became known as potassium.
Potassium Properties.
A. The melting point of Potassium is 63.5 degrees Celsius, about 145 degrees Fahrenheit.
B. The boiling point of potassium is 760 degree Celsius, which is about 1400 degrees Fahrenheit.
C. Potassium reacts violently with water producing potassium hydroxide and hydrogen gas. .
D. Potassium oxidizes as soon as its exposed to air.
Isotopes.
A. Isotope: [N] one of two or more atoms with the same atomic number of neutrons.
B. 17 isotopes of potassium are known.
C. Ordinary potassium is composed of three isotopes.
Production.
A. Potash is mostly mined in Germany, New Mexico, California, and Utah.
B. Potassium is also found in the ocean but is found in small amounts.
C. Metallic Potassium is available commercially for about 40 $ per pound in small quantities.
Uses of potassium.
A. Potassium's most popular use is for fertilizer.
B. Potassium is essential for all living things.
C. Potassium is found in most soils.
D. Potassium is also used in breathing apparatus where moisture in the breath and carbon dioxide reacts with it to release oxygen.
Potassium is a metallic chemical element that is abundant in the earth's crust. ... About 95 percent of the body's potassium is in cells. ... A potassium shortage results in lower levels of stored glycogen. ... You can find potassium in any plant or vegetables because the plants roots take the potassium found in soil and use it to produce foods. ... Many people can handle an excess of potassium if they take to much. ...
Potassium is a mineral greatly needed in every major body function. ... Potassium helps our muscles contract and our heartbeats too. Potassium also helps to make electrolyze. ... Sweating, diarrhea and diuretics weaken potassium. ... Also without potassium, the heart muscle can not beat. ...
Potassium: K Potassium is an element in the periodic table with the symbol K. ... Sir Humphrey David in England discovered potassium in 1807. ... Potassium was the first metal isolated by electrolysis. Potassium is a very important element that has various uses. ... When Potassium reacts with air it forms Potassium hydroxide. ...
Military History and Uses Even though the first to mix potassium nitrate and carbonaceous fuel into an explosive mixture was the Chinese, as they used this invention for fireworks, the true discovers of this magical powder are not fully known. ... Until as late as 1450, gunpowder was a compound made up of more then half potassium nitrate, one quarter sulfur, and one quarter charcoal. ... The change from potassium nitrate to sodium nitrate came when it was discovered that sodium nitrate gave off more energy, and was very inexpensive, as it was easily imported from Chile or Peru. ... The mix...
Purpose To measure the solubility of the given substances (Ammonium Chloride, Potassium Nitrate, Sodium Chloride, Copper Carbonate, Iodine, Sugar, Wax, Sand, Oil, Starch) at various temperatures in water. ... Potassium nitrate is an ionic salt of potassium ions and nitrate ions and is soluble in water because of the separation of positive and negative charges acting on the compound. 7. ... Apparatus - Electrical balance - Hot plate - Boiling tubes - Water - 400ml Beakers - Test tube holder - Thermometer - Stopwatch - Spatula - Stirring rod - Given Substances (Ammonium Chloride, Po...
Potassium is the predominant intracellular cation. This means that serum potassium concentrations are a poor indicator of total body potassium, as only 2% exists in the extracellular fluid. ... In both acidosis and diabetes, the increased potassium loss in the urine due to osmotic diuresis may lead to reduced total body potassium although the plasma potassium levels are increased. ... If excessive dietary potassium intake occurs in renal failure the serum potassium levels will be very high. ... This means that potassium retention will occur. ...
Introduction For this experiment, we used an experimental arrangement of a Gouy balance to measure the susceptibility of various samples. Our theory was that electrons have a magnetic moment that could be aligned with - or opposite - an applied magnetic field, depending on the spin of the electron(...
Car accidents can prove to be fatal. However, with the proper safety measures, fatality can be avoided. Seatbelts can save your life, as well as airbags. An airbag is a big that undergoes a chemical reaction to burst out and causes a stop in motion, pillowing you into it. Airbags are complex, and a ...
There is a recommended daily intake (RDI) for calcium, magnesium, sodium, chloride, and potassium. ... (Hunter-9) The RDI for potassium for both men and women is 2,000 mg. (RDA-137) Potassium is important for the nervous system, muscle function, and fluid balance throughout the body. Potassium is important to the heart and kidney and balances hormones, mainly the adrenal gland. Potassium intake less than 1,600 mg a day can lead to hypokalemia, a deficiency of potassium. ...
