虽然Bates,Robinson等和Stokes等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等指出Zn(固)|Zn~(2+)|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。本文按照前文的办法,选定汞齐中锌的标准态并定义锌汞齐的标准电极电位,利用 Although Bates, Robinson et al. And Stokes et al. Have determined the standard electrode potentials for zinc amalgam, they used saturated zinc amalgam while Clayton et al. Pointed out the electromotive force of Zn (solid) | Zn 2+ (znHg) Is zero, therefore, the above authors did not identify zinc amalgam but zinc as the standard electrode potential, which has been recognized in manuals and textbooks. In this paper, according to the previous approach, the standard state of zinc in amalgam was selected and the standard electrode potential of zinc amalgam was defined.
