Q44 of 136 Page 38

Which reference electrode is used to measure the electrode potential of other electrodes?

Standard hydrogen electrode (SHE) is used as a reference electrode. The potential of SHE is assigned the value zero. The electrode potential of other electrodes are measured with respect to this.

The standard hydrogen electrodes represented by


Pt(s)⎥ H2(g)⎥ H+ (aq)
