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.
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 .
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.
The nitrite ion has the chemical formula NO − 2.Nitrite (mostly sodium nitrite) is widely used throughout chemical and pharmaceutical industries. [1] The nitrite anion is a pervasive intermediate in the nitrogen cycle in nature.
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 .
Silver nitrate is an inorganic compound with chemical formula AgNO 3 . It is a versatile precursor to many other silver compounds, such as those used in photography .
Mercury(II) nitrate is an inorganic compound with the chemical formula Hg(N O 3) 2.It is the mercury(II) salt of nitric acid HNO 3.It contains mercury(II) cations Hg 2+ and nitrate anions NO − 3, and water of crystallization H 2 O in the case of a hydrous salt.
Calcium nitrate are inorganic compounds with the formula Ca(NO 3) 2 (H 2 O) x. The anhydrous compound, which is rarely encountered, absorbs moisture from the air to give the tetrahydrate . Both anhydrous and hydrated forms are colourless salts .
