中学常用乙酸乙酯的水解演示实验。乙酸乙酯是一种有香味的无色透明油状液体。在纯水和通常的无机酸、碱溶液中也呈无色透明状。按照现行高中化学第二册(试验修订本)中所述,采用闻气味的方法来区分乙酸乙酯在不同介质中的水解程度,经过多次实验效果不佳。这主要是因为:其一,实 High school commonly used ethyl acetate hydrolysis demonstration experiment. Ethyl acetate is a scented, colorless, transparent oily liquid. It is also colorless and transparent in pure water and common inorganic acids and alkali solutions. According to the current High School Chemistry Book 2 (Test Revision), the method of smelling odors was used to distinguish the degree of hydrolysis of ethyl acetate in different media. After many experiments, the results were poor. This is mainly because: One, real
