What is the purpose of cooling the reaction mixture during the experiment?

Cooling the reaction mixture during the experiment serves the vital role of preventing heat build-up, particularly in the case of exothermic reactions. When a reaction is exothermic, it releases heat, which can increase the temperature of the reaction mixture. If the temperature rises too high, it could lead to several undesirable outcomes, such as the formation of side products, decomposition of reactants or products, or even a runaway reaction scenario, which can be hazardous.

By cooling the reaction mixture, you help to maintain a stable temperature, allowing for better control over the reaction conditions. This can improve product yield and purity by minimizing the likelihood of side reactions that could occur at elevated temperatures. This practice is essential in laboratory settings where precision and safety are paramount for successful outcomes in syntheses.
