Journal of the American Chemical Society 2010, 132 (41) , 14590-14595. Reduction potential is measured in volts (V) or millivolts (mV). Each species has its own intrinsic reduction potential. The more positive the potential, the greater the species’ affinity for electrons, or the more the species tends to be reduced. Oxidation-reduction in a galvanic cell: In this galvanic cell, zinc reduces copper cations.
(Received March 9, 1987) Abstract The oxidation-reduction potential of Cu(II
Whether reduction or oxidation occurs depends on the potential of the sample versus the potential of the reference electrode. In addition to the SHE, other reference electrodes are the silver–silver chloride electrode; the saturated calomel electrode (SCE); the glass electrode, which is commonly used to measure pH; and ion-selective electrodes, which depend on the concentration of a single
In this study, a custom-designed electrochemical cell is utilized to investigate planar polycrystalline copper as an electrocatalyst for CO reduction under alkaline conditions. Seven major CO reduction products have been observed including various hydrocarbons and oxygenates which are also common CO2 reduction products, strongly indicating that CO is a key reaction intermediate for these further-reduced products. 2016-11-07 · Recall the first reaction we investigated in this tutorial: copper ion has a greater (more positive) reduction potential than zinc, the metallic copper plates out on zinc. Mg 2+ has the most negative potential and metallic magnesium will not plate out on any of the metals in the "reduction tendencies series".
