WebMay 9, 2024 · Figure \(\PageIndex{3}\): Determining a Standard Electrode Potential Using a Standard Hydrogen Electrode. The voltmeter shows that the standard cell potential of a galvanic cell consisting of a SHE and a Zn/Zn 2 + couple is E° cell = 0.76 V. Because the zinc electrode in this cell dissolves spontaneously to form Zn 2 + (aq) ions while H + (aq) … WebThe electrochemical series is built up by arranging various redox equilibria in order of their standard electrode potentials (redox potentials). The most negative E° values are placed …
