The chemical formula K 2 O (or simply 'K') is used in several industrial contexts: the N-P-K numbers for fertilizers, in cement formulas, and in glassmaking formulas. Potassium oxide is often not used directly in these products, but the amount of potassium is reported in terms of the K 2 O equivalent for whatever type of potash was used, such ...
Powdered potassium sulfide anhydrous. Potassium sulfide is an inorganic compound with the formula K 2 S.The colourless solid is rarely encountered, because it reacts readily with water, a reaction that affords potassium hydrosulfide (KSH) and potassium hydroxide (KOH).
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 sulfate (K 2 SO 4) has been known since early in the 14th century.It was studied by Glauber, Boyle, and Tachenius.In the 17th century, it was named arcanuni or sal duplicatum, as it was a combination of an acid salt with an alkaline salt.
Potassium superoxide is a source of superoxide, which is an oxidant and a nucleophile, depending on its reaction partner. [8]Upon contact with water, it undergoes disproportionation to potassium hydroxide, oxygen, and hydrogen peroxide:
Potassium ferrate is a powerful oxidizing agent with applications in green chemistry, organic synthesis, and cathode technology. Synthesis ...
Potassium dichromate, K 2 Cr 2 O 7, is a common inorganic chemical reagent, most commonly used as an oxidizing agent in various laboratory and industrial applications. As with all hexavalent chromium compounds, it is acutely and chronically harmful to health. It is a crystalline ionic solid with a very bright, red-orange color.
Potassium carbonate is the inorganic compound with the formula K 2 C O 3.It is a white salt, which is soluble in water and forms a strongly alkaline solution. It is deliquescent, often appearing as a damp or wet solid.
