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 ...
Expressing resonance when drawing Lewis structures may be done either by drawing each of the possible resonance forms and placing double-headed arrows between them or by using dashed lines to represent the partial bonds (although the latter is a good representation of the resonance hybrid which is not, formally speaking, a Lewis structure).
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 ]

Rocket candy. Rocket candy, or R-Candy, is a type of rocket propellant for model rockets made with a form of sugar as a fuel, and containing an oxidizer. The propellant can be divided into three groups of components: the fuel, the oxidizer, and the (optional) additive (s). In the past, sucrose was most commonly used as fuel.
Liquid junction potential (shortly LJP) occurs when two solutions of electrolytes of different concentrations are in contact with each other. The more concentrated solution will have a tendency to diffuse into the comparatively less concentrated one. The rate of diffusion of each ion will be roughly proportional to its speed in an electric ...
