KOH (aq) + NH 4NO 3 (aq) → NH 3 (g) + H 2O (l) + KNO 3 (aq)įor industrial purpose, it is prepared using double displacement reaction between sodium nitrate and potassium chloride. In addition, one of them is combining ammonium nitrate and potassium hydroxide. Production of Potassium Nitrateĭifferent processes are in use for Potassium nitrate production. It is incapable of dissolving in alcohol and is not poisonous although it can react explosively with reducing agents, but it is not explosive on its own. In aqueous state is almost neutral, exhibiting pH 6.2 at 14 ☌ (57 ☏) for a 10% solution of commercial powder. Potassium nitrate is somewhat soluble in water, but its solubility increases with temperature. Properties of Potassium NitrateĪt room temperature, it has an orthorhombic crystal structure, which transforms to a trigonal system at 129 ☌ (264 ☏). Its main use is, in the nitric acid industry and manure works. Now we manufacture it from atmospheric nitrogen. On the walls of stables, calcium nitrate was once common as an efflorescence. Chile saltpeter is in use mainly in the nitric acid industry and particularly as a fertilizer. Sodium nitrate occurs, under the same conditions as ordinary saltpeter, in deposits covering immense areas in South America, abounding especially in the regions of Tarapacá and Antofagasta in Chile. Potassium nitrate is white in color and soluble in water it has a vitreous luster and a cool and salty taste. Potassium nitrate occurs naturally on the surface of the Earth, on walls and rocks, and inside caves and it forms in certain soils in Spain, Italy, Egypt, Iran, and India. Now we shall study briefly about the different Saltpeters.

These three nitrates generally occur as efflorescence, which forms by the oxidation of nitrogenous matter in the presence of the alkalis and alkaline earth. It is categorized as (1) Ordinary saltpeter, or potassium nitrate, KNO 3 (2) Chile saltpeter, cubic niter, or sodium nitrate, NaNO 3 and (3) Lime saltpeter, wall saltpeter, or calcium nitrate, Ca(NO 3) 2. In the early time before systematic naming of chemicals, saltpeter has another name as nitrate of potash. Depending on where you live, it may be spelled “saltpeter” rather than ‘saltpeter’. Saltpeter or potassium nitrate, KNO 3 is a natural mineral source found on earth. 1.8 Solved Question for You Saltpeter or Potassium Nitrate
