Ammonium nitrate Formula

Formula and structure: The chemical formula of ammonium nitrate is NH 4 NO 3 Its molecular formula is written as N 2 H 4 O 3 and its molar mass is 80 052 g/mol Ammonium nitrate is a salt which consists of two ions: a cation the ammonium ion (NH 4 +) and an anion the nitrate ion (NO 3-) The cation and anion are held together by a strong ionic bond

Ammonium removal

Except from regular-used processes like ion exchange it is found that reverse osmosis desalination membranes can be applied to achieve surprisingly high ammonium removal from drinking water This rejection can reach even the 97% depending on the membrane that is used the operational characteristics of the system as well as the quality of feed water

Ammonium Ion Concentration in the Primitive Ocean

If ion exchange on clay minerals regulated the cationts in the primitive ocean as it does in the present ocean the pH would have been 8 and the K+ concentration 0 01M Since NH4+ and K+ are similar in their claymineral equilibria the maximum NH4 + concentration in the primitive ocean would also have been 0 01M An estimate of the minimum NH4+ concentratin is 1 x 10-3M based on the

Ammonium Ion Binding to DNA G

Ammonium ion loss at some late stage of electrospray (when solvent is still present) can be ruled out because based both on the melting temperatures and on the ammonium ion exchange rates the solution-phase stability of bimolecular G-quadruplexes in solution ranks in the following way: (dG 4 T 3 G 4) 2 (dG 4 T 4 G 4) 2 (dG 3 T 4 G 4) 2 In the ESI-MS spectra ammonium ion preservation
