months, with a very slight decrease in titre, by using an automatic equipment for the supplying with carbon dioxide of the storage flask and burette. The procedure has so far been employed for the determination of ferric-, ferrous-, dichromate-, vanadate-, bromate-, iodate- and ferricyanide ions, furthermore of iodine. The advantage of the method is — in addition to the simplicity of the realization —
摘要 阐述了一种普遍适用的还原方法,通过该方法可以测定氧化电位超过 0.3 V 的多种物质。 0.1 N 氯化亚锡标准溶液可以储存数月,滴定度略有下降。用于供应储存瓶和滴定管二氧化碳的设备。迄今为止,该程序已用于测定三价铁、亚铁、重铬酸盐、钒酸盐、溴酸盐、碘酸盐和铁氰化物离子,以及碘。该方法的优点是——除了实现简单之外——在给定的范围内,实验误差永远不会超过 0.5%,通常保持在这个限制之下。
