3. a) You'll saponify your oil by combining it with equal volumes of 95% ethanol and 25% sodium hydroxide. As the reactants are the oil and aqueous sodium hydroxide, what's the purpose of adding 95% ethanol to the reaction mixture? b) Which of the saponification reactants do you need to handle with care, and why? c) What's the purpose of adding a saturated sodium chloride solution to the saponification mixture after the reaction is complete?
