Potassium chloride (KCl, or potassium salt) is a metal halide salt composed of potassium and chlorine. It is odorless and has a white or colorless vitreous crystal appearance. The solid dissolves readily in water, and its solutions have a salt-like taste. Potassium chloride can be obtained from ancient dried lake deposits. [7]
In practice, potassium chloride (also known as potassium salt) is the most commonly used salt substitute. Its toxicity for a healthy person is approximately equal to that of table salt (the LD 50 is about 2.5 g/kg, or approximately 190 g for a person weighing 75 kg).
The use of a salt substitute can provide a taste offsetting the perceived blandness of low-salt food; potassium chloride is widely used for this purpose. The World Health Organization (WHO) recommends daily potassium intake of not less than 3,510 mg. [ 18 ] Government interventions such as food product reformulation and food procurement policy ...
Potassium hydroxide is used for industrial water treatment and is the precursor of potassium carbonate, several forms of potassium phosphate, many other potassic chemicals, and soap manufacturing. Potassium carbonate is used to produce animal feed supplements, cement , fire extinguishers , food products, photographic chemicals , and textiles.
The most commonly used catalyst is a mixture of potassium chloride and aluminum chloride. However, various forms of porous carbon can also be used. This reaction produces tetrachloroethylene as a byproduct and depending on the amount of chlorine fed to the reaction, tetrachloroethylene can even be the major product.
Chemical hazards are usually classified separately from biological hazards (biohazards). Chemical hazards are classified into groups that include asphyxiants, corrosives, irritants, sensitizers, carcinogens, mutagens, teratogens, reactants, and flammables. [1] In the workplace, exposure to chemical hazards is a type of occupational hazard.
Potassium-magnesium sulfate double salt, a good fertilizer, is a salt that precipitates from bitterns upon addition of methanol. [3] Ethanol is also used, but it exhibits a preference for potassium sulfate precipitation. [3] The solution can furthermore be used in the production of potash and potassium salts. [10]
Major potassium chemicals are potassium hydroxide, potassium carbonate, potassium sulfate, and potassium chloride. Megatons of these compounds are produced annually. [72] KOH is a strong base, which is used in industry to neutralize strong and weak acids, to control pH and to manufacture potassium salts.
