李比希是19世纪德国一位著名的化学大师,对无机化学、有机化学、生物化学都曾有过重大贡献,被西欧许多国家评为科学院院士或名誉院士。就是这样一位名人,竟有一件事让他抱憾终生。1826年,年仅24岁的巴拉还只是某大学化学系的一位无名小卒,在实验室担任实验员。他在用氯水和淀粉处理黑角菜灰烬时,发现滤液分上下两层,下层呈蓝色,其中含有碘,上层色深黄且带微红。这是什么物质呢?巴拉百思不得其解,但他对这一疑点没有草率放过,连续做了多种 Liebig was a famous German master of chemistry in the 19th century. He had made significant contributions to inorganic chemistry, organic chemistry, and biochemistry. He was honored as a member of the Academy of Sciences or an honorary academician in many countries in Western Europe. It is such a celebrity that there is one thing that makes him regret for life. In 1826, Bara, who was only 24 years old, was still an unknown soldier in the chemistry department of a university and worked as a laboratory technician in the laboratory. When he treated ash ash with chlorine water and starch, he found that the filtrate was divided into two layers, the lower layer was blue, which contained iodine, the upper layer was dark yellow and reddish. What kind of material is this? Bara Balth cannot be understood, but he has not spared this doubt and has done a lot of things in a row.
