Lab 12: Saponification – Making Soap Objective: To make soap using the process call saponification, an organic form of the neutralization reaction that an acid reacts with a base to form a salt. Introduction: A soap is the sodium or potassium salt of a long chained carbohydrate called a fatty acid. A fatty acid usually contains between 12 – 18 carbon atoms. Fatty acids are esters of either animal or vegetable fats. They are called triglycerides if they are solids at room...
lab report on the preparation of soap (Saponification) 1. Write the reaction for the saponification of glyceryl tripalmitate with sodium 2. 3. 4. hydroxide. Why is the product of saponification called a salt? Why was ethanol added to the reaction mixture of fat and base? Do you think the solid soap that you made contains glycerol? Why or why not? Explain. 5. Describe the appearance of your soap. 6. Explain how soaps emulsify oils and fats. 7. Explain why soaps...
u Question 18 Which of the following is used in saponification? O soap O weak base O strong base O strong acid
In the saponification process, what is the purpose of thoroughly mixing the fat with sodium hydroxide? A. To raise the pH of the mixture and drive the reaction towards equilibrium B. To produce an emulsion in which there is a greater surfac area upon which the sodium hydroxide can react with the fat molecules C. To separate the soap molecules from the water to promote ease of filtering D. To generate distinctly separate layer of fat and sodium hydroxide E....
draw the condensed formula of the base hydrolysis of ethanol acid and sodium 7) Draw the condensed formula of the base hydrolysis (saponification) of ethanoic acid and sodium hydroxide
What could I have done wrong in the saponification of the ester? I did not get soap 1.) Place .18 g of saturated triglyceride in a 5 mL short necked round bottom flask. 2.)Add 1.5 mL of a 50-50 water ethanol solution that contains .18 g of sodium hydroxide. 3.)Add an air condenser and gently reflux mixture on sand bath for 30 minutes Do not boil away ethanol -At the end of their reaction period, some of this soap will...
