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 .
Sal petrae (Med. Latin: "stone salt")/salt of petra/saltpetre/nitrate of potash – potassium nitrate, KNO 3, typically mined from covered dungheaps. Salt/common salt – a mineral, sodium chloride, NaCl, formed by evaporating seawater (impure form). Salt of tartar – potassium carbonate; also called potash.
Potassium nitrate is an oxidizer so storing it near fire hazards or reducing agents should be avoided to minimise risk in case of a fire. Product Identification [ edit ]
A saltpetre works or nitrary [1] is a place of production of potassium nitrate or saltpetre used primarily for the manufacture of gunpowder. The saltpeter occurs naturally in certain places like the "Caves of Salnitre" ( Collbató ) known since the Neolithic.
Saltpeter (or saltpetre) is the mineral form of potassium nitrate (KNO 3), a compound It may also sometimes refer to: Sodium nitrate (NaNO 3), a compound Chile saltpeter or nitratine, the mineral form; Norwegian saltpeter or calcium nitrate (Ca(NO 3) 2) Magnesium nitrate (Mg(NO 3) 2)
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.
sodium nitrate produces a yellow/orange color, potassium nitrate and rubidium nitrate produce violet colors, caesium nitrate produces an indigo color. In a general way, the emitted color progressively turns from the red to the violet in the visible spectrum of light when going down in the column of the alkaline metals in the periodic table of ...
The three main components of black powder are charcoal, sulfur, and saltpeter (or potassium nitrate). It is known that, by 1045, the Chinese were producing black powder, because many references to the subject were found in The Wu-ching Tsung-Yao (Complete Compendium of Military Classics). [ 2 ]
