IUPAO规定:E=((+)-(-) 如:标准锌电极与标准氢电极组成原电池,锌为负 极,氢为正极,测得ε=0.7618(V),则 p(Zn21/n)=0.0000-0.7618=0.7618(V) Switch Voltmeter Zn anode thode compartment No (standard 3 hydrogen Anode z 2+ NO lectrode compartment NO. H zn(s)→zn2+(aq)+2e-2Htaq+2e-→H2g)
IUPAC 规定： ε＝ φ (+) – φ(-) 如：标准锌电极与标准氢电极组成原电池，锌为负 极，氢为正极，测得 ε ＝ 0.7618 (V) , 则 φ(Zn 2+/Zn) = 0.0000 – 0.7618 = -0.7618(V)
