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.
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.
Many different sugars are used as the fuel for rocket candy. The most common fuel is typically sucrose, however, glucose and fructose are sometimes used. As an alternative, sorbitol, a sugar alcohol commonly used as a sweetener in food, produces a propellant with a slower burn rate and is less brittle when made into propellant grains. [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.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

Sodium nitrate is a white deliquescent solid very soluble in water. It is a readily available source of the nitrate anion (NO 3 − ), which is useful in several reactions carried out on industrial scales for the production of fertilizers , pyrotechnics , smoke bombs and other explosives , glass and pottery enamels , food preservatives (esp ...
The nitric oxide produced may react with atmospheric oxygen to give nitrogen dioxide. With more concentrated nitric acid, nitrogen dioxide is produced directly in a reaction with 1:4 stoichiometry: Cu + 4 H + + 2 NO − 3 → Cu 2+ + 2 NO 2 + 2 H 2 O. Upon reaction with nitric acid, most metals give the corresponding nitrates.
