先前有关高离子强度对极谱研究影响的理论考虑已应用于混合的一价硝酸盐惰性电解质系统以及还原电位与电毛细管最大值不同的系统。结果表明，在解释高离子强度对极谱数据的影响时，此类系统中的水合是一个重要的考虑因素。这些作者之前的工作表明，观察到的硝酸镉半波电位的变化（假设可还原物质和惰性电解质之间没有络合）是惰性电解质的活度系数和水活度的函数。更可用的近似形式被表述为
Application of previous theoretical considerations concerning the influence of high ionic strength on polarographic investigations has been applied to systemsof mixed, uni-univalent nitrate inert electrolytes and to systems whose reduction potential is different from that ofthe electrocapillary maximum. It is shown that hydration in such systems is an important considerationin the interpretation of the effect of high ionic strength on polarographic data.Previous work by these authors1 has shown that the observed change in the half-wave potential for cadmium nitrate (assuming no complexation between the re-ducible species and the inert electrolyte) is a function of the activity coefficient of the inert electrolyte and the activity of water. The more usable approximate form has been stated as
