Potassium nitrate is a chemical compound with a sharp, salty, bitter taste and the chemical formula K N O 3. It is a potassium salt of nitric acid . This salt consists of potassium cations K + and nitrate anions NO − 3 , and is therefore an alkali metal nitrate .
Potassium nitrite (distinct from potassium nitrate) is the inorganic compound with the chemical formula K N O 2. It is an ionic salt of potassium ions K + and nitrite ions NO 2 −, which forms a white or slightly yellow, hygroscopic crystalline powder that is soluble in water. [1] It is a strong oxidizer and may accelerate the combustion of ...
Elemental potassium does not occur in nature because it reacts violently with water. [34] As part of various compounds, potassium makes up about 2.6% of the Earth's crust by mass and is the seventh most abundant element, similar in abundance to sodium at approximately 1.8% of the crust. [35]
Potassium nitrate – KNO 3; Potassium perbromate – KBrO 4; Potassium perchlorate – KClO 4; Potassium periodate – KIO 4; Potassium permanganate – KMnO 4; Potassium sodium tartrate – KNaC 4 H 4 O 6; Potassium sulfate – K 2 SO 4; Potassium sulfite – K 2 SO 3; Potassium sulfide – K 2 S; Potassium tartrate – K 2 C 4 H 4 O 6 ...
In contact with potassium nitrate (e.g. in black powder) produces potassium perchlorate and hygroscopic ammonium nitrate; no such reaction with sodium nitrate. Reacts with potassium chlorate, producing unstable, gradually decomposing ammonium chlorate; such combination has to be avoided. [1] Nitronium perchlorate
Niter or nitre [5] is the mineral form of potassium nitrate, KNO 3.It is a soft, white, highly soluble mineral found primarily in arid climates or cave deposits. Historically, the term niter was not well differentiated from natron, both of which have been very vaguely defined but generally refer to compounds of sodium or potassium joined with carbonate or nitrate ions.
3 anion) depends on the basicity of the metal, and so do the products of decomposition (thermolysis), which can vary between the nitrite (for example, sodium), the oxide (potassium and lead), or even the metal itself depending on their relative stabilities. Nitrate is also a common ligand with many modes of coordination. [19]
In general, potassium compounds are ionic and, owing to the high hydration energy of the K + ion, ... Only a very few fertilizers contain potassium nitrate. [64]
