Many of the salts which have been prepared are explosive and sensitive to heat or impact. These include chlorites of copper (violent on impact), hydrazine (monochlorite, inflames when dry), nickel (explodes at 100°C but not on impact), silver (at 105° or on impact), sodium, tetramethylammonium, mercury, thallium and lead (which shows detonator properties). Several other chlorites not isolated and unstable in solution include mono-, di- and tri-methylammonium chlorites. The metal salts are powerful oxidants [1], Chlorites are much less stable than the corresponding chlorates, and most will explode under shock or on heating to around 100°C [2], Individually indexed compounds are ... 

The methods commonly used for preparation of disodium dihydrogen hypophosphate depend upon the oxidation of yellow or red phosphorus. Yellow phosphorus may be oxidized by air1 or by copper(II) nitrate.2,3 Red phosphorus may be oxidized by chlorite,4 hypochlorite,5,6 alkaline permanganate,7 hydrogen peroxide,7 or iodine.8 The phosphorus (III) halides, upon hydrolysis and treatment with iodine, yield some hypophosphate.9-11 Electrolytic oxidation of a phosphide of copper, nickel, or silver3 has also been used. 

Catalysis of these reactions has been reported . At pH 3.5, cupric ion is said to catalyse the process (1) and ferric ion, the process (2). The latter appears to be third order in chlorite. Nickel and cobalt salts had less selective action. The first-order reactions reported by Ishi involve rate coefficients comparable to those above and thus the orders may be wrong. The maximum yield of CIO2 near pH 2, which was found by Buser and Hanisch , has been confirmed . A low order (1.69) in chlorate was found with acetate buffers and may be explained by the above mechanism. Further studies in this pH region are required, but it is likely that the process initiated by (11) is predominant, and produces CIO2 more rapidly than either (3) or (10) .

Chlorite is common in sedimentary rocks and in productive soils derived therefrom. The elemental composition of chlorites varies widely, however, with chromium and nickel occurring in mafic (Fe- or Mg-containing) chlorites. Serpentine-derived soils contain chlorite and many are infertile because of their high Mg and low Ca contents.
