在高校试用教材《无机化学实验》(中山大学、辽宁大学等校编,人民教育出版社1978年出版)实验四十四,三氯化六氨合钴(Ⅲ)组成的测定存在以下几个问题。在蒸馏过程中,容易发生倒吸,常使实验半途而废;装置较复杂,操作不方便;花时间多。为此我们设计了一套实验装置,将氨和钴的测定改进如下。 Experiments in Inorganic Chemistry in Colleges and Universities (edited by Sun Yat-sen University, Liaoning University, People’s Education Press, published in 1978) Experiment forty-four, and there are several problems in the determination of hexaammine hexahydrate cobalt (III) composition. . In the distillation process, sucking easily occurs, often leaving the experiment halfway; the device is more complex and inconvenient to operate; it takes more time. For this purpose we have designed a set of experimental devices that will improve the determination of ammonia and cobalt as follows.
