摘要
阐述双核配合物[(NH_3)_5CoO_2Co(NH_3))_5]^(4+)的形成、性质及应用,同时介绍一种在混合气体中测定氧的新方法.在常温和常压下,用[Co(NH_3)_5(H_2O)]^(2+)的水溶液处理一定体积的空气,空气的体积减小21.03%,此值与空气中氧含量相一致.这说明[Co(NH_3)_5(H_2O)]^(2+)与 O_2在水溶液中的反应是一定全反应.
The article explicates the formation,the properties and the application af two—nucLear complex [(NH_3)_5CoO_2Co(NH_3)_5]^(4+) and introduces a new method of determination of oxygen in mixtures of gases. At normal atmospheric temperature and at atmospheric pressure for a given volume of air treated with aqueous solu- tion of [Co(NH_3)_5(H_2O)]^(2+),the volume of air went down by 21.03%.This value is the same with that of the oxygenic content in the air. The results indicate that the reaction between [Co(NH_3)_5(H_2O)]^(2+) and Q_2 in aqueous solution is a complete reac- tion.
