"For all half-reactions the conc species and the pressure is I atm for gases.These are the standard-state values.The more positive E°red , the stronger the oxidizing agent on the left side. The more positive the E°red , the greater the electron￾pulling power of the half reducing reaction. Page:1128 The more negative of E°red , the stronger the reducing agent on the right side. The more negative the E°red, the greater the electron￾donating power of the half reducing reaction. oxidizing agent reducing agent oxidation state / reduction state
