Oxidizing and Reducing Agents - Chemistry LibreTexts

WebA The possible reduction products are Mg and K, and the possible oxidation products are Cl 2 and Br 2. Because Mg is more electronegative than K (χ = 1.31 versus 0.82), it is likely that Mg will be reduced rather than K. Because Cl is more electronegative than Br (3.16 versus 2.96), Cl 2 is a stronger oxidant than Br 2. WebThe potential required to oxidize Cl - ions to Cl 2 is -1.36 volts and the potential needed to reduce Na + ions to sodium metal is -2.71 volts. The battery used to drive this reaction must therefore have a potential of at least 4.07 volts. This example explains why the process is called electrolysis . flags of war 28mm
