Reduction of Metal Oxide to Metal – Introduction, …

Consider the following reaction: 2 [Fe(CN)6] + Cl 2 → 2 [Fe(CN)6] + 2 Cl The reducing agent in this reaction is ferrocyanide ([Fe(CN)6] ). It donates an electron, becoming oxidized to ferricyanide ([Fe(CN)6] ). Simultaneously, that electron is received by the oxidizer chlorine (Cl 2), which is reduced to chloride (Cl ). 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 .

Web7 de mai. de 2024 · Lithium metal is therefore the strongest reductant (most easily oxidized) of the alkali metals in aqueous solution. The standard reduction potentials can be interpreted as a ranking of substances … 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.
