Web7 de abr. de 2024 · Iron can be obtained by reduction with carbon. Thus, the oxides of highly reactive metals cannot be reduced by carbon. Thus, highly reactive metal cannot be obtained from their oxides by heating them with carbon. Note: The highly reactive metals like potassium, sodium, calcium and aluminium are more reactive than carbon. 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 .
