有些杰出的科学家,往往就因为一时的粗心,放过了重大发现的机会,以致后悔莫及。化学元素“溴”的发现就是一例。德国科学家巴里阿尔在一次实验中,得到了一种褐色液体,与常见的氯化碘非常相似。但是巴里阿尔没有粗心大意,没有按照常规把它当做已知氯化物放在一边,而是对这样褐色液体进行了细心的观察和提纯实验,证明了它并不是人们熟悉的氯化碘,而是一种未知的新元素溴。这个发现震动了当时的化学界。为此,著名的德国化学家利比希深感内疚。原来,他
Some eminent scientists tend to regret because of the temporary carelessness they have missed the major discovery. The discovery of the chemical element “bromine” is one example. Barrière, a German scientist, got an brownish liquid in an experiment very similar to the usual iodine chloride. But Barrial, without any carelessness, aside from routinely treating it as a known chloride, carefully examined and purified such a brown liquid, proving that it was not the familiar iodine chloride but rather An unknown new element of bromine. This discovery shakes the chemistry of the time. For this reason, the famous German chemist Libic deeply guilty. It turned out that he
