虽然Bates[1],Robinson等[2]和Stokes等[3]曾确定锌汞齐的标准电极电位,但他们用的是饱和锌汞齐,而Clayton等[4]指出Zn(固)|Zn2+|znHg(饱和)的电动势为零,因此,以上诸作者确定的并不是锌汞齐而是锌的标准电极电位,这点已为手册和教科书所承认。

The standard state of zinc in amalgam is so chosen that the activity coefficient of zinc wi!! be unity as the mole fraction of zinc approaches zero. According to this standard state, the activity coefficients of zinc in amalgam were obtained from the data of Pearce and Eversole[6]:
15℃ r=1-4.64N2+7.0N22 where N2 is the mole fraction of zinc in amalgam.
