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]
Potassium chlorate is the inorganic compound with the molecular formula KClO 3. In its pure form, it is a white solid. After sodium chlorate, it is the second most common chlorate in industrial use. It is a strong oxidizing agent and its most important application is in safety matches. [6]
For example, KMgCl 3 is named magnesium potassium trichloride to distinguish it from K 2 MgCl 4, magnesium dipotassium tetrachloride [105] (note that in both the empirical formula and the written name, the cations appear in alphabetical order, but the order varies between them because the symbol for potassium is K). [106]
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.
Common name Chemical name (Formula) Potash fertilizer: Up to the early 20th century:potassium carbonate (K 2 CO 3). Beginning from the late 19th century: one or more of potassium chloride (KCl), potassium sulfate (K 2 SO 4) or potassium nitrate (KNO 3).
Potassium cyanide is a compound with the formula KCN. It is a colorless salt, similar in appearance to sugar, that is highly soluble in water. Most KCN is used in gold mining, organic synthesis, and electroplating. Smaller applications include jewellery for chemical gilding and buffing. [4]
An example is table salt, which is sodium chloride with the chemical formula NaCl. In water, it dissociates into Na + and Cl − ions. Salts such as calcium chloride, magnesium chloride, potassium chloride have varied uses ranging from medical treatments to cement formation. [4]
Potassium perchlorate is the inorganic salt with the chemical formula K Cl O 4. Like other perchlorates , this salt is a strong oxidizer when the solid is heated at high temperature although it usually reacts very slowly in solution with reducing agents or organic substances.
