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.
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 ]
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 ...
In the NO − 3 anion, the oxidation state of the central nitrogen atom is V (+5). This corresponds to the highest possible oxidation number of nitrogen. Nitrate is a potentially powerful oxidizer as evidenced by its explosive behaviour at high temperature when it is detonated in ammonium nitrate (NH 4 NO 3), or black powder, ignited by the shock wave of a primary explosive.
Molten salts (fluoride, chloride, and nitrate) can be used as heat transfer fluids as well as for thermal storage. This thermal storage is used in concentrated solar power plants. [8][9] Molten-salt reactors are a type of nuclear reactor that uses molten salt (s) as a coolant or as a solvent in which the fissile material is dissolved.
In chemistry, a salt or ionic compound is a chemical compound consisting of an assembly of positively charged ions (cations) and negatively charged ions (anions), [ 1 ] which results in a compound with no net electric charge (electrically neutral). The constituent ions are held together by electrostatic forces termed ionic bonds.
Sodium nitrate is the chemical compound with the formula Na N O 3. This alkali metal nitrate salt is also known as Chile saltpeter (large deposits of which were historically mined in Chile) [ 4 ][ 5 ] to distinguish it from ordinary saltpeter, potassium nitrate.
