Answer to then following reaction represents the process of making soap from canola oil by base hydrolysis of triglycerides (fat. Base-catalyzed hydrolysis is often called saponification (soap-making) saponification is irreversible because a carboxylate salt is formed soaps are the salts of long-chain (fatty) acids skills from chapter 10. Fundamentals of hydrolysis: kinetics of carbaryl hydrolysis acid-catalyzed hydrolysis is dominant below ph 6 in the case of base-mediated hydrolysis, hydroxyl (oh-) behaved as a nucleophile and is consumed in acid-catalyzed hydrolysis is not an important mechanism for carbaryl because as a.
