If for the half cell reaction cu2+
WebThe potential of a concentration cell is given by the Nerst equation. The 1 millimolar compartment is the anode: C u X ( s) C u X 2 X + X ( a q) + 2 e X − and the 1 M compartment is the cathode C u X 2 X + X ( a q) + 2 e X − C u X ( s) For a concentration cell Eo is zero because both compartments are identical. WebScientists create a galvanic cell in which one half-cell contains the half-reaction to be determined. The other half-cell is a standard hydrogen electrode (SHE) in which the half-reaction is: 2H⁺ + 2e⁻ = H₂ E° for the SHE is defined as 0.00 V. Then E° for the half-reaction is the same as the measured value of E° for the cell.
