What is the effect of the presence of H2O in the test for Liebermann Burchardt reaction?

In the Liebermann-Burchardt reaction, the presence of water (H2O) can hinder the formation of the characteristic colored product, typically a blue or green compound, which indicates the presence of phenolic compounds. Water can dilute the reaction mixture, reducing the concentration of reagents and possibly leading to incomplete reactions. Additionally, excess water may lead to hydrolysis of intermediates, preventing the desired complex from forming. Therefore, controlling moisture levels is crucial for accurate results in this test.
