VI. Calculate the saponification equivalent of ethyl acetate. State all assumptions and show all work. Include the complete balanced equation for the reaction. VII. 2.00 g of an unknown mono-ester is hydrolyzed by refluxing with 50.0 mL of 0.500 M NAOH until the reaction is complete. The reaction mixture is cooled and an indicator is added to the still basic solution. Titration to end point with 0.200 M HCl required 48.1 mL. a. How many moles of hydroxide remained after hydrolysis of the ester? Show all work including complete balanced equation for the reaction. b. How many moles of hydroxide were consumed in the hydrolysis? Show all work. c. Calculate the saponification equivalent of the unknown ester. Show all work. d. Which ester below is the most likely candidate for the unknown? Why? i. ethyl ethanoate ii. Phenyl benzoate iii. Isopentyl acetate 68
