In the NO − 3 anion, the oxidation state of the central nitrogen atom is V (+5). This corresponds to the highest possible oxidation number of nitrogen. Nitrate is a potentially powerful oxidizer as evidenced by its explosive behaviour at high temperature when it is detonated in ammonium nitrate (NH 4 NO 3), or black powder, ignited by the shock wave of a primary explosive.
The positive ion retains its element name whereas for a single non-metal anion the ending is changed to -ide. Example: sodium chloride, potassium oxide, or calcium carbonate. When the metal has more than one possible ionic charge or oxidation number the name becomes ambiguous. In these cases the oxidation number (the same as the charge) of the ...
The nitrate ion. 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 3) to 414 °C (CsNO
3 anion) depends on the basicity of the metal, and so do the products of decomposition (thermolysis), which can vary between the nitrite (for example, sodium), the oxide (potassium and lead), or even the metal itself depending on their relative stabilities. Nitrate is also a common ligand with many modes of coordination. [19]
The reason for adding gelatin is that it removes metal ions such as Cu 2+ that catalyses the destruction of hydrazine by reaction with monochloramine (NH 2 Cl) to produce ammonium chloride and nitrogen. [59] Hydrogen azide (HN 3) was first produced in 1890 by the oxidation of aqueous hydrazine by nitrous acid. It is very explosive and even ...
In the simplest case, the cation is a metal atom and the anion is a nonmetal atom, but these ions can be more complex, e.g. molecular ions like NH + 4 or SO 2− 4. In simpler words, an ionic bond results from the transfer of electrons from a metal to a non-metal to obtain a full valence shell for both atoms.
A metalloid is an element that possesses a preponderance of properties in between, or that are a mixture of, those of metals and nonmetals, and which is therefore hard to classify as either a metal or a nonmetal. This is a generic definition that draws on metalloid attributes consistently cited in the literature.
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]
