Ammonium Chlorite

Ammonium Chlorite, NH4C102, pale yel, transparent crysts, mp dec rapidly on heating. According to Mellor(Ref 1), this compd was first obtd in soln by N.Millon(184 3) on saturating an aq soln of chlorous acid with ammonia. Levi(Ref 2) prepd the compd in the form of delq ndls which exploded on percussion on an anvil... 

Chlorites are strong oxidizing snbstances. They, however, are less stable than the chlorates. They are sensitive to heat or impact. Most metal chlorites explode npon heating at 100-HOT (212-230°F). Sodinm chlorite does or explode on percussion. Mixtures of chlorites with finely divided metals or organic compounds may burst into flame on friction. Ammonium chlorite explodes when subjected to heat or shock, as does silver chlorite, AgC102 [7783-91-7]. 

Ethylene glycol combusted spontaneously when it was added to potassium permanganate at ambient temperature and at 100°C in the presence of ammonium or potassium dichromate, sodium chlorite or silver chlorate. With potassium dichromate, the medium reached 170°C.

The adsorption of transition metal complexes by minerals is often followed by reactions which change the coordination environment around the metal ion. Thus in the adsorption of hexaamminechromium(III) and tris(ethylenediamine) chromium(III) by chlorite, illite and kaolinite, XPS showed that hydrolysis reactions occurred, leading to the formation of aqua complexes (67). In a similar manner, dehydration of hexaaraminecobalt(III) and chloropentaamminecobalt(III) adsorbed on montmorillonite led to the formation of cobalt(II) hydroxide and ammonium ions (68), the reaction being conveniently followed by the IR absorbance of the ammonium ions. Demetallation of complexes can also occur, as in the case of dehydration of tin tetra(4-pyridyl) porphyrin adsorbed on Na hectorite (69). The reaction, which was observed using UV-visible and luminescence spectroscopy, was reversible indicating that the Sn(IV) cation and porphyrin anion remained close to one another after destruction of the complex.

Notice in Table 6-1 that all the common polyatomic ions except ammonium have a negative charge ranging between -1 and -3. You also see a number of -ite/-ate pairs, such as chlorite and chlorate, phosphite and phosphate, and nitrite and nitrate. If you look closely at these pairs, you notice that the only difference between them is the number of oxygen atoms in each ion. Specifically, the -ate ion always has one more oxygen atom than the -ite ion but has the same overall charge. 

Divalent Pd forms many planar complexes with a coordination number of 4. The tetrachlorides aie quite soluble, When a solution of palladium(II) chloride is oxidized with chlorite or chlorate ion, Pd(IV) is formed, which has a coordination number of 8, The addition of NH4Q to such a solution precipitates ammonium hexachloropalladate(IV) as a red compound. It is somewhat less stable than the platinum analog.

The product can be checked for the presence of chlorine by testing the output stream with the fumes from ammonium hydroxide chlorine produces the typical white cloud of ammonium chloride, while chlorine(IV) oxide does not. No chlorine is present in the effluent gas until two-thirds or more of the sodium chlorite has reacted, at which time chlorine may escape through channels in the remaining sodium chlorite without reacting.
