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.
Sodium nitrate is the chemical compound with the formula Na N O 3. This alkali metal nitrate salt is also known as Chile saltpeter (large deposits of which were historically mined in Chile) [4] [5] to distinguish it from ordinary saltpeter, potassium nitrate. The mineral form is also known as nitratine, nitratite or soda niter.
Ammonium nitrate is a chemical compound with the formula NH 4 NO 3. It is a white crystalline salt consisting of ions of ammonium and nitrate . It is highly soluble in water and hygroscopic as a solid, although it does not form hydrates .
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. It occurs in nature as a mineral, niter (or nitre outside the US). [5]
The chemical element nitrogen is one of the most abundant elements in the universe and can form many compounds. It can take several oxidation states; but the most common oxidation states are -3 and +3. Nitrogen can form nitride and nitrate ions. It also forms a part of nitric acid and nitrate salts.
Iron(III) nitrate, or ferric nitrate, is the name used for a series of inorganic compounds with the formula Fe(NO 3) 3. (H 2 O) n. Most common is the nonahydrate Fe(NO 3) 3. (H 2 O) 9. The hydrates are all pale colored, water-soluble paramagnetic salts.
Barium nitrate is the inorganic compound with the chemical formula Ba(NO 3) 2. It, like most barium salts, is colorless, toxic, and water-soluble. It burns with a green flame and is an oxidizer; the compound is commonly used in pyrotechnics. [4]
The term "calcium ammonium nitrate" is applied to multiple different, but closely related formulations. One variety of calcium ammonium nitrate is made by adding powdered limestone to ammonium nitrate; [1] [2] another, fully water-soluble version, is a mixture of calcium nitrate and ammonium nitrate, which crystallizes as a hydrated double salt: [3] 5Ca(NO 3) 2 •NH 4 NO 3 •10H 2 O.
