A simple example of a polyatomic ion is the hydroxide ion, which consists of one oxygen atom and one hydrogen atom, jointly carrying a net charge of −1; its chemical formula is O H −. In contrast, an ammonium ion consists of one nitrogen atom and four hydrogen atoms, with a charge of +1; its chemical formula is N H + 4.
The Solvay Process as an example of a cyclic process in chemical industry (green = reactants, black = intermediates, red = products) The Solvay process results in soda ash (predominantly sodium carbonate (Na 2 CO 3 )) from brine (as a source of sodium chloride (NaCl)) and from limestone (as a source of calcium carbonate (CaCO 3 )).

A carbonate is a salt of carbonic acid, (H 2 CO 3), [2] characterized by the presence of the carbonate ion, a polyatomic ion with the formula CO 2− 3. The word "carbonate" may also refer to a carbonate ester , an organic compound containing the carbonate group O=C(−O−) 2 .
Sodium carbonate (also known as washing soda, soda ash and soda crystals) is the inorganic compound with the formula Na 2 CO 3 and its various hydrates.All forms are white, odourless, water-soluble salts that yield alkaline solutions in water.
However when counting electrons, negative ions should have extra electrons placed in their Lewis structures; positive ions should have fewer electrons than an uncharged molecule. When the Lewis structure of an ion is written, the entire structure is placed in brackets, and the charge is written as a superscript on the upper right, outside the ...
In chemistry, isomerization or isomerisation is the process in which a molecule, polyatomic ion or molecular fragment is transformed into an isomer with a different chemical structure. [1] Enolization is an example of isomerization, as is tautomerization .
For example a range from 1.4 to 2.2 Na 2 SO 4 •Na 2 CO 3 is stable as a solid solution. [2] Silvialite can substitute about half its sulfate with carbonate [ 3 ] and the high temperature hexagonal form of sodium sulfate (I) Na 2 SO 4 can substitute unlimited proportions of carbonate instead of sulfate.
Polyatomic ions generated within the plasma can have larger atomic radii than analyte ions of similar mass, i.e. the interferent NaAr + (mass 63) is larger than the analyte Cu + (mass 63). Thus, when using a collisional/reactive gas mixture, these larger species undergo more collisions/reactions in the cell, in which they lose increasingly more ...
