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 ]
Potassium bicarbonate has widespread use in crops, especially for neutralizing acidic soil. [11]Potassium bicarbonate is an effective fungicide against powdery mildew and apple scab, allowed for use in organic farming.
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 ]

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.
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 ...
Gunpowder is a low explosive: it does not detonate, but rather deflagrates (burns quickly). This is an advantage in a propellant device, where one does not desire a shock that would shatter the gun and potentially harm the operator; however, it is a drawback when an explosion is desired.
