引言和研究计划在给定酸存在下，铈盐和铈盐的等摩尔混合物的氧化电位随共同阴离子的性质而变化，在一定程度上随酸的浓度而变化。Bauer和Glaessner的粗略测量表明，在硝酸溶液中该电位为1.84伏，在硫酸溶液中为1.70伏。后来，Kunz 2对硫酸铈-硫酸铈在硫酸溶液中的氧化电位进行了彻底而准确的研究。他从他的结果中得出结论，氧化电位，指摩尔氢电极为零，在1.0摩尔的酸溶液中为1.4435伏，在0.5摩尔的酸溶液中为1.4442伏。这似乎表明，两种浓度的硫酸之间的电位几乎没有变化。
Introduction, and Plan of Investigation The oxidation potential of an equimolal mixture of cerous and ceric salts of a given acid in the presence of that acid varies considerably with the nature of the common anion andto some extent with the concentration of the acid. Crude meas-urements of Bauer and Glaessner1 showed this potential to be 1.84 volts in nitric acid solution and 1.70 volts in sulfuric acid solution. Later Kunz2 made a thorough and accurate study of the oxidation potential of cerous-ceric sulfates in solutions of sulfuric acid. He concluded from his results that the oxidation potential, referred to the molal hydrogen electrode as zero, is 1.4435 volts in 1.0 molal, and 1.4442 volts in 0.5 molal acid solution. This seems to show that there is little change in the potential between the two concentrations of sulfuric acid.
