Weband exhibit evidently only one couple of redox peaks which corresponds to the redox reaction between VO2+ and VO 2 +. However, the oxidative and reductive peak currents … Webredox couples consisting of metals and their ions. One of the couples will be Zn2+/Zn. From Equations 1 - 3, we know that copper(II) is reduced in this reaction, so the Cu2+/Cu couple is the cathode. However, when the Cu2+/Cu couple is connected to the Ag1+/Ag couple, the Cu2+/Cu couple is the anode. What e ect will this have on the measurement? WebRedox (reduction–oxidation, / ˈ r ɛ d ɒ k s / RED-oks, / ˈ r iː d ɒ k s / REE-doks) is a type of chemical reaction in which the oxidation states of substrate change. Oxidation is the loss of electrons or an increase in the oxidation state, while reduction is the gain of electrons or a decrease in the oxidation state..
