How can metal like na and k be reduced
Web31 de mai. de 2024 · Potassium and sodium are strong electropositive metals and have great affinity for oxygen than that of carbon. Hence they Cannot be extracted from their … 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 .
