Theoxidation state(or oxidation number) of an atom as a free element, or in a compound or an ion represents its hypothetical charge, assuming all bonds are ionic. The change of oxidation states of an atom through a reaction indicate if the atom has lost or gained electrons through ...
作者: EG Ball,TT Chen,With the technical assistance of W. Mansfield Clark 摘要: Dilatometrical indication can be applied to oxidation-reduction reactions; this is demonstrated by the following oxidation-reduction couples: K2Cr2O7/FeSO4, K2Cr2O7/Na3AsO3, Ce(SO4)2/FeSO4, Ce(SO4)2/Na3AsO3. Amo...
It is found that the degradation of TCP by Cu(II)/H2O2/Cl− system followed pseudo first-order kinetics (Fig. S1) under the most experimental conditions. Fig. 1b and c show that the degradation rate of TCP, expressed as the observed pseudo first-order rate constant k, increased as Cu...
