Together with nitrogen and phosphorous, potassium is one of the essential macrominerals for plant survival. Skin and eye contact can cause severe burns leading to permanent damage. Higher exposures may cause a build up of fluid in the lungs, this can cause death. Inhalation of dust or mists can irritate the eyes, nose, throat, lungs with sneezing, coughing and sore throat. Potassium can effect you when breathed in. When our kidneys are somehow malfunctioning an accumulation of potassium will consist. Potassium, as the ion K+, concnetrate inside cells, and 95% of the body's potassium is so located. It plays an important role in the physical fluid system of humans and it assists nerve functions. Potassium can be found in vegetables, fruit, potatoes, meat, bread, milk and nuts. Although it is soluble in water, little is lost from undisturbed soils because as it is released from dead plants and animal excrements, it quickly become strongly bound to clay particles, and it is retained ready to be readsorbed by the roots of other plants. The world production of potassim ores is about 50 million tonnes, and reserves are vast (more than 10 billion tonnes). Today most potassium minerals come from Canada, USA and Chile. The main mining area used to be Germany, which had a monopoly of potassium before the first World War. Minerals mined for their potassium are pinkish and sylvite, carnallite and alunite. Potassium is leached from these by weathering, which explains why there is quite a lot of this element in the sea (0.75 g/liter). Most potassium occurs in the Earth's crust as minerals, such as feldspars and clays. In all cases it is the negative anion, not the potassium, which is the key to their use. Other potassium salts are used in baking, photography and tanning leather, and to make iodize salts. A little potassium chloride goes into pharmaceuticals, medical drips and saline injections. Potassium carbonate goes into glass manufacture, expecially the glass used to make televisions, while potassium hydroxide is used to make liquid soaps and detergents. Most potassium (95 %) goes into fertilizers and the rest goes mainly into making potassium hydroxide (KOH), by the electrolysis of potassium chloride solution, and then converting this to potassium carbonate (K 2CO 3). The chemistry of potassium is almost etirely that of the potassium ion, K +. It is light enough to float into water with which it reacts instantly to release hydrogen, which burns with a lilac flame. Potassium is silvery when first cut but it oxidizes rapidly in air and tarnishes within minutes, so it is generally stored under oil or grease. Potassium is a soft, silvery-white metal, member of the alkali group of the periodic chart. The chemical symbol K comes from kalium, the Mediaeval Latin for potash, which may have derived from the arabic word qali, meaning alkali. The name is derived from the english word potash.
