性质:又称参考电极或标准电极(standard electrode)。测定各种电极的电极势时所选用的电极势已知且稳定性和重现性好的电极(也要求其温度系数小、电流通过时极化电位及机械扰动的影响小)。常用的有标准氢电极、银-卤化银电极、甘汞电极、氢醌电极等。测定时,将被测电极与参比电极组成原电池,测出其电动势。若εx, εr, E分别为待测电极势、参比电极电极势和电池电动势,则有E=εxr。于某参考电极的电极势,加上该参比电极相对于氢标(以标准氢电极的电极势等于零为标准)的电极势,即可换算出该电极相对于氢标的电极势。例如,以饱和甘汞电极为参比电极测得某电极的电极势为0.618V。因饱和甘汞电极相对于氢的电极势为0.415V,故可知,该电极相对于氢标的电极势为0.033V。
