redox potentials

Redox potentials measure how likely a substance is to gain or lose electrons during a chemical reaction, indicating its tendency to be reduced or oxidized. A positive redox potential suggests a substance readily gains electrons (reduction), while a negative value means it prefers to lose electrons (oxidation). These values help predict how different substances will react with each other, such as in batteries or biological processes, by showing which substance will act as an electron acceptor or donor under specific conditions.
