Оценка термодинамической вероятности взаимодействия соединений никеля с восстановителями и окислителями

Abstract

Theoretical studies have been carried out to evaluate the thermodynamic probability of the interaction of nickel compounds with various oxidizing agents and reducing agents. It was established that in the interaction of nickel compounds with HCOOH, HCOH, H2, CH4, the release of metal is thermodynamically impossible. It is shown that when using the oxidizing agent KMnO4, it is possible to oxidize divalent nickel compounds to Ni3O4 and Ni2O3. It has been reported that using H2O2 as an oxidizing agent, nickel oxides may be formed.
