摘　　要：通过比较Fe^2＋和Fe（OH）2在空气中被氧化的标准平衡常数和各自组成原电池负极电对的标准电极电位以及电动势的大小，从理论上对何者容易在空气中被氧化作了初步的分析和探讨。This paper analyzed ferrous ion and ferrous hydroxide which was more easily oxidized in the air, based on comparing the standard equilibrium constants of the oxidation reactions, standard electrode potential of negative electrode pair and electromotive force of primary battery formed by the relevant reactions.

关 键 词：亚铁离子 氢氧化亚铁 电极电位 还原性强弱 标准平衡常数
