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]
Sylvite, or sylvine, is potassium chloride (KCl) in natural mineral form. It forms crystals in the isometric system very similar to normal rock salt, halite (NaCl). The two are, in fact, isomorphous. [5] Sylvite is colorless to white with shades of yellow and red due to inclusions. It has a Mohs hardness of 2.5 and a specific gravity of 1.99.
Potassium chloride, also known as potassium salt, is used as a medication to treat and prevent low blood potassium. [2] Low blood potassium may occur due to vomiting, diarrhea, or certain medications. [3] The concentrated version should be diluted before use. [2] It is given by slow injection into a vein or by mouth. [4]
Potassium is a chemical element; it has symbol K (from Neo-Latin kalium) and atomic number 19. It is a silvery white metal that is soft enough to easily cut with a knife. [9] Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure.
Potassium chlorite is a potassium salt of chlorous acid (HClO 2) having a chemical formula KClO 2. It exists as white powder and its annhydrous form easily undergoes decomposition in presence of heat or radiation (especially gamma rays ).
With further heating, potassium perchlorate decomposes to potassium chloride and oxygen: KClO 4 → KCl + 2 O 2. The safe performance of this reaction requires very pure reagents and careful temperature control. Molten potassium chlorate is an extremely powerful oxidizer and spontaneously reacts with many common materials such as sugar.
The most abundant ion in plant cells is the potassium ion. [2] Plants take up potassium for plant growth and function. A portion of potassium uptake in plants can be attributed to weathering of primary minerals, but plants can also ‘pump’ potassium from deeper soil layers to increase levels of surface K. [2] Potassium stored in plant matter can be returned to the soil during decomposition ...
User:Doc James recently contested the claim that potassium chloride is harmless in food. Since it is uncited and I can see it being problematic to a layman ("harmless" is a much stronger claim than "not lethal"!), I could see a further verification/citation as a good thing.
