A completely inorganic oscillating system of the Belousov–Zhabotinskii type

Abstract

An inorganic compound, NaHzPOz, has been found to generate temporal chemical oscillations in Belousov-Zhabotinskii type reactions when it is substituted for the organic reducing material. Gaseous products were removed by a constant flow of nitrogen carrier gas. Periodic Brz evolution was measured polarographically.

The Chlorate–Nitrous Acid–Iodine–Iodide Oscillating Reaction

“…They can be pH oscillators, 12−14 oscillators that produce periodic luminescence, 15 some reactions can be affected by light 16,17 or oxygen, 18 and many other aspects can be considered as a criterion. Among several possibilities, the classification by the oxidant component is one of the most common, and in this case, the biggest group is the bromatedriven oscillating reactions, 19,20 which is based on modifications of the BZ reaction 3,4 by changing the original malonic acid by other organic 21−23 or inorganic compounds 24 or by changing (or eliminating) the original metal-ion catalyst. 9 Another big family of oscillating reactions is based on chlorite.…”
