  2. Potassium nitrate - Wikipedia

    en.wikipedia.org/wiki/Potassium_nitrate

    Infobox references. 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 ]

  3. Potassium nitrite - Wikipedia

    en.wikipedia.org/wiki/Potassium_nitrite

    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] It is a strong oxidizer and may accelerate the combustion of ...

  4. Alkali metal nitrate - Wikipedia

    en.wikipedia.org/wiki/Alkali_Metal_Nitrate

    Alkali metal nitrates are chemical compounds consisting of an alkali metal (lithium, sodium, potassium, rubidium and caesium) and the nitrate ion. Only two are of major commercial value, the sodium and potassium salts. [1] They are white, water-soluble salts with melting points ranging from 255 °C (LiNO. The melting point of the alkali metal ...

  5. Cerium nitrates - Wikipedia

    en.wikipedia.org/wiki/Cerium_nitrates

    The potassium salt, Ce 2 K 3 (NO 3) 9 can be made by using the water solution of potassium nitrate and cerous nitrate in 3:2 molar ratio, evaporated at 40 °C. The crystals are colourless cubic from space group P4 1 32. Its formula weight is 955.6. Three formulas exist in each unit cell which at 20 °C, has a volume of 2514.1 Å 3 and cell side ...

  6. Nitrate - Wikipedia

    en.wikipedia.org/wiki/Nitrate

    Nitrate is a polyatomic ion with the chemical formula NO−3. Salts containing this ion are called nitrates. Nitrates are common components of fertilizers and explosives. [ 1 ] Almost all inorganic nitrates are soluble in water. An example of an insoluble nitrate is bismuth oxynitrate.

  7. Labeling of fertilizer - Wikipedia

    en.wikipedia.org/wiki/Labeling_of_fertilizer

    The NPK analysis label. Fertilizers are usually labeled with three numbers, as in 18-20-10, indicating the relative content of the primary macronutrients nitrogen (N), phosphorus (P), and potassium (K), respectively. More precisely, the first number ("N value") is the percentage of elemental nitrogen by weight in the fertilizer; that is, the ...

  8. Rocket candy - Wikipedia

    en.wikipedia.org/wiki/Rocket_candy

    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.

  9. Molar mass - Wikipedia

    en.wikipedia.org/wiki/Molar_mass

    M N−1. In chemistry, the molar mass (M) (sometimes called molecular weight or formula weight, but see related quantities for usage) of a chemical compound is defined as the ratio between the mass and the amount of substance (measured in moles) of any sample of the compound. [1] The molar mass is a bulk, not molecular, property of a substance.
