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.
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] It is a source of nitrogen, and nitrogen was named ...
Nitrogen compounds. 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.
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 ...
Nitrite is the conjugate base of the weak acid nitrous acid: Nitrous acid is also highly volatile, tending to disproportionate: This reaction is slow at 0 °C. [2] Addition of acid to a solution of a nitrite in the presence of a reducing agent, such as iron (II), is a way to make nitric oxide (NO) in the laboratory.
A common nitrate test, known as the brown ring test[2] can be performed by adding iron (II) sulfate to a solution of a nitrate, then slowly adding concentrated sulfuric acid such that the acid forms a layer below the aqueous solution. A brown ring will form at the junction of the two layers, indicating the presence of the nitrate ion. [3]
Tetranitratoborate is an anion composed of boron with four nitrate groups. It has formula [B (NO3)4]−. It can form salts with large cations such as tetramethylammonium nitratoborate, [1] or tetraethylammonium tetranitratoborate. [2] The ion was first discovered by C. R. Guibert and M. D. Marshall in 1966 after failed attempts to make neutral ...
Orthonitrate is a tetrahedral anion of nitrogen with the formula NO3−. 4. It was first identified in 1977 [1] and is currently known in only two compounds, sodium orthonitrate (Na 3 NO 4) and potassium orthonitrate (K 3 NO 4). The corresponding oxoacid, orthonitric acid (H 3 NO 4), is hypothetical and has never been observed.
