Infobox references. Potassium nitrate is a chemical compound with a sharp, salty, bitter taste and the chemical formula K N O 3. It is an ionic salt of potassium ions K + and nitrate ions NO 3−, and is therefore an alkali metal nitrate. It occurs in nature as a mineral, niter (or nitre outside the US). [ 5 ]
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.
Amine value. In organic chemistry, amine value is a measure of the nitrogen content of an organic molecule. [1] Specifically, it is usually used to measure the amine content of amine functional compounds. [2] It may be defined as the number of milligrams of potassium hydroxide (KOH) equivalent to one gram of epoxy hardener resin.
Another laboratory process is the reaction of lithium nitrate LiNO 3 and bromine pentafluoride BrF 5, in the ratio exceeding 3:1. The reaction first forms nitryl fluoride FNO 2 that reacts further with the lithium nitrate: [8] BrF 5 + 3 LiNO 3 → 3 LiF + BrONO 2 + O 2 + 2 FNO 2 FNO 2 + LiNO 3 → LiF + N 2 O 5
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 ...
Alkali metal nitrates are chemical compounds consisting of an alkali metal (lithium, sodium, potassium, rubidium and caesium) and the nitrate ion. Only two are of major commercial value, the sodium and potassium salts. [1] They are white, water-soluble salts with melting points ranging from 255 °C (LiNO. The melting point of the alkali metal ...
Salt bridge. An electrochemical cell (resembling a Daniell cell) with a filter paper salt bridge. The paper has been soaked with a Potassium nitrate solution. In electrochemistry, a salt bridge or ion bridge is an essential laboratory device discovered over 100 years ago. [1] It contains an electrolyte solution, typically an inert solution ...
