The oxidation state (number) is a positive or negative integer value assigned to an atom when it is part of a chemical compound, compound ion or simple ion. We specify these three types of particles because the pure standard state of the element receives a reference oxidation state of zero....
The rate followed first-order kinetics in [oxidant] and fractional order in [TSC] in both the pure state and in the metal complex with all the oxidants. With chloramine T, the rate had an inverse first-order and inverse fractional order dependence in [H+] for two ranges of [HClO4], ...
What is the oxidation number of chlorine in HClO_4? (a) 0 (b) +7 (c) -1 (d) -3. What is the oxidation number of chlorine in HClO4? Determine the oxidation state of oxygen in the compound Cr2O3 in the following equation. Cr2O3(s) + Al(s) arrow Cr(s)...
The electrocatalytic oxidation of formic acid at a gold electrode functionalized with FePt nanoparticles was studied by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) in a mixed solution of 0.1 M HCOOH and 0.1 M HClO4. The FePt bimetallic nanoparticles, with a mean diamet...
Selective oxidation reactions are usually catalyzed by metal ions having more than one oxidation state, which are easily accessible with common oxidizing agents. Most of the increasing interest in these reactions comes from the search for new catalysts, which aim at the preparation of more valuable ...
The photolysis primary stage (R1) was approximated as a reaction of first kinetic order with respect to ozone. Its rate constant was calculated with the formulak1 = φ254 · NΦ · ε254 · ln10/(60 · NA), s−1, where φ254 = 0.55 (Reisz et al. 2003...
The oxide I species produced as the initial oxidation product by successively more anodic potentiostatic oxidation in 0.2 M HClO 4 is found to have a Pt 2+ oxidation state, a binding energy characteristic of neither PtO, Pt(OH) 2 or PtO 2, and a limiting thickness of 8 . Galvanostatic ...
It has been observed that the state or structure of Pt surfaces is influenced by the chemical nature of the atmosphere, whether reductive (Ar/H2, Ar/CO, etc.), oxidative (air, Ar/air, etc.), or neutral (Ar, Ar/N2, etc.), used for cooling flame-annealed Pt crystals [12,13]. ...
The effect of solvent (aqueous solutions of HClO4 and H2SO4) on the low-temperature (T < 273 K) reaction of U(IV) with XeF2, accompanied by formation of uranyl ion in the electronically excited state *(UO 2 2+ ), was examined. In the course of heating of 0.2–8.31 M HClO4 ...
