新编高中化学课本,乙酸乙酯水解实验仍然用闻乙酸乙酯气味的浓淡,来确定乙酸乙酯在酸性,碱性和中性不同溶液里的水解情况。这样的实验方法是欠妥的。现作如下改进,既方便简单,现象明显,又科学合理,效果较好。
In the new high school chemistry textbook, the ethyl acetate hydrolysis experiment still used the smell of ethyl acetate to determine the hydrolysis of ethyl acetate in different acidic, alkaline, and neutral solutions. This experimental method is not proper. Now make the following improvements, both convenient and simple, obvious phenomenon, but also a scientific and rational, the better.
