德国化学家李比希是１９世纪最优秀的化学家之一，农业化学的创立者，被誉为德国“化学之父”。在一次提取碘的实验中，他用海藻灰做原料，在浸出液中通入氯气后，碘元素析了出来，实验完成后，李比希发现烧杯底中有一些深褐色的液体，他几乎没有想一下，就认为这是氯化钾，很 The German chemist Liebig, one of the finest chemists in the 19th century, the founder of agrochemicals, is reputed as the “father of chemistry” in Germany. In an experiment of extracting iodine, he used seaweed ash as a raw material. After the chlorine gas was introduced into the leachate, the iodine was separated out. After the experiment was completed, Li Bixi found some dark brown liquid in the bottom of the beaker, and he almost did not think about it , Think this is potassium chloride, very
