Reduction potential meaning
The reduction potential is a measure of the tendency of the oxidizing agent to be reduced. Its value is zero for H + + e − → 1 ⁄ 2 H 2 by definition, positive for oxidizing agents stronger than H + (e.g., +2.866 V for F 2) and negative for oxidizing agents that are weaker than H + (e.g., −0.763 V for Zn 2+).: 873In today’s digital age, email has become an essential means of communication.
