What is the oxidation number of hydrogen in HPO32-? Determine the oxidation number of each element in HClO4. In the reaction AlCl3 + Na arrow NaCl + Al, did Al change its oxidation number? Explain. How do you determine if 2Al(s) + 3Br2(l) arrow 2AlBr3(s) is...
Because oxidation of carbohydrates is subject to HSO4- ion catalysis, HClO4 was used, as in our earlier studies, in the present investigation to minimize the number of different catalyzing species.doi:10.1080/07328309208017801Kiviniemi, Anne-Marja...

The electrochemical oxidation of aromatic compounds spontaneously and irreversibly adsorbed from solution onto smooth polycrystalline platinum electrodes has been studied as a function of adsorbate orientation. Experiments were done in aqueous 1 M HClO4 at ambient temperatures using thin-layer electrochemical ...
The Hatta number has been calculated with the formula Ha = \( \sqrt{D_{O3}{k}_{1,O3}/{k}_L} \)(Beltran2004), whereDO3is ozone diffusion coefficient in aqueous solution,DO3 = 2 × 10−9m2s−1(Beltran2004),kLis the mass transfer coefficient, in the analogous reac...
electrocatalytic stability of these catalysts was assessed by accelerated durability tests (ADTs), which were also carried out at room temperature in O2-saturated 0.1 M HClO4 electrolyte using cyclic voltammetry between 1.0 and 0.4 V at a sweep rate of 100 mV s−1 for a given number of ...
To prepare the analytical solution, 5 mg of the py-RuO2:Zn powder scraped off the Ti substrate was dispersed in 20 mL solution containing HNO3, HCl, and HClO4 with the ratio of 4:12:3, then transferred into a hydrothermal 50 mL Teflon-lined stain- less-steel autoclave. Finally, the ...
precious Pt metal by diminishing the number of its buried nonfunctional atoms, and the increase in activity could be attributed mainly to the larger surface area of the hollow structure, where the porous or open shell allows the internal surface of the catalyst to be accessible to the reactant...
