Potassium 3 is the main component of potash. It is usually present in the earth's crust in combination with other minerals, especially where there are considerable quantities of clay minerals and heavy soils. Potash is a contaminated mixture of potassium carbonate and potassium salt. It is used in agriculture as a fertilizer and cleanser for soil. The term "potash" also refers to any one of several chemical compounds that can be obtained by leaching ashes from wood with water: K 2 O, Rb 2 O, Cs CO 3, Na 2 O, or NH 4 OH.
The world production of potash was about 1.5 million tons in 2005. Canada is the largest producer followed by Russia and Kazakhstan. United States is the second largest producer.
Canada's Potash Corporation of America is the largest producer of potash in the United States. Texas Brine LLC acquired the Potash Corporation of America in 2004 for $340 million. In September 2008, Texas Brine filed for bankruptcy protection after suffering billions of dollars in damages when an underground brine pool formed by a former potash mine collapsed in Titusville, Florida.
China's leading producer of potash is Sinopec Shanghai Chemical Company with sales of nearly $1 billion. Japan's third largest potash producer is Nippon Chemicals, which operates four plants in Japan.
Potassium is the main component of potash. Potassium is a member of the alkali metal group and is found in abundance in nature. It is used in many products, such as glass, candy, toilets, and batteries. Potassium does not react with water molecules but instead forms hydrogen gas and potassium hydroxide.
Alkalis are substances that have the ability to form salts with acids. Alkalis contain equal numbers of electrons in their valence shells which means they can be classified as electronegative elements. This means that alkalis have the ability to donate electrons to other substances causing them to become acidic. Alkalis include sodium, potassium, lithium, and rubidium. Other elements that share this property but are not considered alkalis include ammonia (NH3), silicon (Si), phosphorus (P), sulfur (S), antimony (Sb), arsenic (As), tin (Sn), and zinc (Zn). Ammonia is used in household products such as cleansers and fertilizers. Silicon is used in semiconductors, while phosphorous is used in flame retardants and pesticides. Sulfur is used in chemicals for cleaning oil wells, sodium is used as a flux in steel production, and zinc is used in corrosion protection products.
Potash is a mineral group that consists of potassium salt combined with impure potassium carbonate (K2CO3). Potash derives from the Dutch term "potasch," which originally referred to wood ash. The word is now used for any potassium-rich mineral.
Wood ash contains approximately 70% potassium, while rock salt has 35% potassium. Therefore, potash is simply wood ash that has had most of the sodium removed. It can be made by heating wood in a kiln or furnace until it becomes white powder, and then mixing it with water to make a salty syrup that is allowed to cool and solidify.
The most common use for potash is as a fertilizer. It helps plants absorb nutrients such as nitrogen, phosphorus, and potassium. Some farmers apply potash to wheat fields before or after planting to help the crops grow better. The potash increases the soil's ability to retain moisture during dry periods and promotes deeper root growth, which ensures greater yield during future growing seasons.
When making soap, some people substitute half the amount of sodium hydroxide (lye) with equal amounts of potassium hydroxide (wood ash). This works well because they are both alkalis, but you still need to adjust the pH of your soap to avoid burning your skin.
Potash is the general term for any potassium-containing substance, including potassium carbonate (K2CO3), potassium oxide (K2O), and potassium chloride (KCl). These chemicals are largely employed in the production of fertilizer. Potash is derived from the Dutch word potaschen, which meaning "pot ashes." The term was originally applied to a poisonous alkali metal compound found in pot ash or pot scum.
Potash has several chemical names. It is also known as rock salt, sal soda, sal ammoniac, and lye. Its chemical formula is K+OH−. When dissolved in water it forms a weak acid, called potassium hydroxide (KOH).
The first part of this name, potash, arose because this mineral was used by early chemists to test their experiments, just like modern scientists use sodium and potassium salts to study reactions. The word potash comes from the Dutch potasschen, which means "pot ash." The English word is based on the German Ganssauge-Potasche, which in turn comes from the Latin ganos stibium or ganstibium-potasscus. This name refers to the use of this mineral for testing metals, just like the ancient Greeks and Romans used arsenic to test bronze.
In chemistry, potassium compounds are essential components of fertilizers. They provide nutrients that help plants grow.
Potassium carbonate, K2CO3, or potash (1), dissolves readily in water and forms an alkaline solution. The chemical element potassium got its English and French names from the term potash. K2CO3 was given the name potash because it was derived from wood ash that had been leached off by water in a pot. The word "pot" being the British spelling of the letter P.
Bituminous coal when burned produces carbon dioxide and smoke. The gas can be absorbed by lime to produce calcium carbonate, which is used for cement and plaster. The remaining solid waste is called slag. Slag contains small amounts of aluminum, silicon, oxygen, iron, and magnesium.
Lime has many industrial applications. It is used as a soil acidifier and detergent stabilizer. In the production of glass, limestone removes harmful impurities from the glass material before it is melted into glass. The purified glass is then used for various containers such as bottles and jars. Lime is also used as a filler material for making hollow plastic objects. This is important since it increases the volume of the object without adding extra weight.
Calcium carbonate has many useful properties. It makes good mortar when mixed with water and sand or gravel and used as a building material. Calcium carbonate also makes good concrete when combined with water and sand or gravel.
The distinction between potash and lime is that potash is an impure form of potassium carbonate (k2co3) combined with other potassium salts, whereas lime is a broad name for inorganic calcium materials, mainly calcium oxide or calcium hydroxide, which is quicklime. The two substances are used in almost identical ways because they have very similar properties. They can be used to improve soil structure, increase water retention, and promote plant growth.
Lime has many uses including fertilizer because of its ability to react with acid gases such as sulfur dioxide from coal combustion or nitrogen oxides from industrial processes. This reaction produces a solid product that is easy to dispose of and free of any odor. It also reduces the amount of acid gases in the air which would otherwise cause problems for people who suffer from asthma or other respiratory diseases.
Potash is used in farming because it contains nutrients that help plants grow. It contains potassium, which helps plants maintain their healthy shape and resist pests, while also providing food for bacteria and fungi which are good for the soil. Potash is also used as a non-food crop because it can be sold for money. Some farmers extract potash from spent brewery grains or tobacco leaves and sell it for profit. This is called potash mining and it is done mostly in Canada and America.
