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 is a colorless to white mineral crystallizing in the orthorhombic crystal system. It is the mineral form of potassium nitrate, KNO3, [ 6 ] and is soft (Mohs hardness 2), [ 7 ] highly soluble in water, [ 6 ] and easily fusible. Its crystal structure resembles that of aragonite, with potassium replacing calcium and nitrate replacing ...
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 ]

Flash powder. Flash powder is a pyrotechnic composition, a mixture of oxidizer and metallic fuel, which burns quickly (deflagrates) and produces a loud noise regardless of confinement. It is widely used in theatrical pyrotechnics and fireworks (namely salutes, e.g., cherry bombs, M-80s, firecrackers, and cap gun shots) and was once used for ...

Chemical nomenclature. Chemical nomenclature is a set of rules to generate systematic names for chemical compounds. The nomenclature used most frequently worldwide is the one created and developed by the International Union of Pure and Applied Chemistry (IUPAC). IUPAC Nomenclature ensures that each compound (and its various isomers) have only ...
