There have been experiments on the hydrolysis of ethyl acetate and sodium hydroxide
. The reason is that ethyl acetate ($CH_3COOC_2H_5 $) reacts with sodium hydroxide ($NaOH $). The two contact, the ester bond breaks, and the reaction is sodium acetate ($CH_3COONa $) and ethanol ($C_2H_5OH $). The reaction formula is as follows: $CH_3COOC_2H_5 + NaOH\ longrightarrow CH_3COONa + C_2H_5OH $.

At the beginning of the experiment, prepare all the things. Take a clean container, measure the number of ethyl acetate, and take an appropriate amount of sodium hydroxide solution, and slowly pour it in. At first, the two are mixed, and there is no big difference. However, after a while, there is a subtle change. From the sense of smell, gradually smell the unique mellow aroma of ethanol, and cover the reaction.

Looking at the reaction process, the temperature change cannot be ignored. This hydrolysis reaction is slightly heated, causing the temperature of the solution to rise slightly. And the concentration of sodium hydroxide also affects the speed of the reaction. If its concentration is high, the reaction will tend to be fast; if the concentration is low, the reaction will be slow.

As for the degree of reaction, over time, ethyl acetate will gradually decrease until it is almost complete into sodium acetate and ethanol. After the reaction is completed, the quality and quantity of the product can be known by chemical testing, and the details of this hydrolysis reaction can be known. This is an example of chemical change, which is useful in various fields of chemical engineering and scientific research, and can help scholars understand the wonders of chemical change.
