Why is potassium nitrate also called nitre?
Potassium nitrate is also called nitre because historically, it was derived from deposits of potassium nitrate salt found in caves. These natural deposits of potassium nitrate were known as nitre beds or nitre caves. The term "nitre" is still used today to refer to potassium nitrate in some contexts.
How do you make spirit of nitre?
traditionally made thru the distillation of potassium nitrate. It is nitric acid
What is the method of separating mixture of nitre and common salt?
A method of separation may be the fractional crystallization.
What are nitre-beds?
Nitre beds have been used for years to make potassium nitrate, they consist of manure, ash and urine. They stacked the "ingredients" on a bed of clay then left it till it formed a white crust, this was then removed and washed with water, this got rid of the other soluble products. They used then potassium nitrate to make gunpowder.
Where did nitrogen get its name?
The name "nitrogen" comes from two Latin words meaning "nitre-forming", nitre being potassium nitrate (saltpetre). Daniel Rutherford, the Scottish doctor who discovered nitrogen in 1772, dubbed it "noxious air" or "fixed air".The chemist Lavoisier called it azote, from the Greek for "lifeless", because nitrogen seemed inert. This name can still be seen in some modern names of compounds, such as hydrazine. Also, it can be called "burnt air" meaning "air without oxygen".It came from the term nitre, an alternative name for saltpeter (potassium nitrate).nitrogen=nitre+gen=nitre maker
Is nitre is an element mixture and a compound?
i think so nitre is a compound

What does nitre mean in 'The Cask of Amontillado'?
In "The Cask of Amontillado," nitre refers to potassium nitrate, a chemical compound often found on damp walls in old buildings. Its presence in the catacombs where the story takes place helps to create a dark and eerie atmosphere.
Is there a virtual wolf world?
Immortal Night and Nitre. http://www.immortalnight.com http://www.nitre.webs.com But Nitre isn't finished yet. Nitre is a downloadable werewolf game and it is not finished. Immortal Night lets you choose between a Vampire and a werewolf, and it is online. Immortal Night needs Internet, but Nitre doesn't. Here is how they are pronounced: Immortal Night (Imm or toll ni t) Nitre (Ni tree)
Common name for potassium nitrate?
nitre, saltpeter(KNO3), Chile saltpeter(NaNO3)

How do you separate the constituents of gun powder?
Gunpowder is a mixture of nitre (potassium nitrate) , sulpher and charcoal Name of the method- filteration , evaporation and solvent extraction. Steps- 1) Put the constituents in water. nitre will dissolve in water. 2) Filter the soln. Filterate- water+nitre Residue - sulpher+charcoal 3) Perform evaporation on the filterate. Water will evaporate leaving nitre. Solvent extraction- 4) Put the residue in carbon disulphide. Sulpher will dissolve in this soln. 5) Filter the soln. Filterate-carbon disulphide+sulpher Residue- charcoal 6) Perform evapooration on the filterate. carbon disulphide evaporates leaving sulpher.

Outline process for separating the three components of gunpowder.?
Gunpowder is a mixture of nitre (potassium nitrate) , sulphur and charcoalName of the method- filteration , evaporation and solvent extraction.Steps-1) Put the constituents in water. nitre will dissolve in water.2) Filter the soln.Filterate- water+nitreResidue - sulphur+charcoal3) Perform evaporation on the filterate.Water will evaporate leaving nitre.Solvent extraction-4) Put the residue in carbon disulphide.Sulphur will dissolve in this soln.5) Filter the soln.Filterate-carbon disulphide+sulphurResidue- charcoal6) Perform evaporation on the filterate.carbon disulphide evaporates leaving sulphur.in the form of a paragraph:-Answer: Gunpowder is a mixture of sulphur, charcoal and potassium nitrate (nitre). When water is added to the mixture potassium nitrate dissolves. The mixture is then filtered. The filtrate is potassium nitrate solution while the residue is a mixture of sulphur and charcoal. The filtrate is evaporated on a sand bath to obtain nitre back. When carbon disulphide is added to the residue, sulphur dissolves. When this mixture is filtered the filtrate is sulphur solution while the residue is charcoal. Leaving it open evaporates the sulphur solution. Carbon disulphide evaporates and sulphur crystals are left behind.
What kind of salt is used in making fire works?
Salt Petre, also called Nitre, or Potassium Nitrate.
