saponification of coconut oil with NaOH
1. What is the nucleophile in this reaction?
hydroxide???
2. Why doesn’t sodium acetate act as soap?
Sodium acetate cannot be used as soap because there is no
non-polar hydrocarbon side component long enough to bind nonpolar
dirt fats or oils. Without this organic component it cannot be used
as soap.???

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...

7.(2 pts.) In your experiment, sodium bisulfite in water is used to destroy any unreacted bromine, Brz, or to TRAP the Bra and not allow it to escape from the reaction. The reaction is shown below but can't be described using conventional organic curved-arrow pushing. After adding sodium bisulfite in your procedure, why is the resulting mixture put into acid waste? - Na* "HSO3 + Br2 + H20 sodium bisulfite Na* "HSO4 + 2 HB sodium bisulfate

Suppose you were given a mixture of n-octane, sodium iodide and water to separate. Using the information gathered for these and similar compounds in this experiment, and using what you know about the properties of these materials from other contexts, outline a procedure that could be used to do a quantitative separation of these three materials. Your procedure should be specific enough, that if followed, someone could determine the amount (mass) of each of the three materials present in the...

2. Why do ionic substances with higher lattice energies tend to be less soluble in water than substances with lower lattice energies? 3. Which would you expect to have the larger hydration energy, SO or CIOA? Explain. 4. Ethyl alcohol, CH CH2OH, is miscible with water at 20°C, but pentyl alcohol, CH3CH2CH2CH2CH2OH, is soluble in water only to the extent of 2.7 g/100 ml. Explain.

Questions and Exercises 1. In the course of reflux of the triglyceride in a sodium hydroxide solution you will notice a lot of foaming. Explain. What is left behind in the aqueous layer after filtration of the saponification product? The starting material and the product of the saponification reaction have similar melting points. How do you know you actually isolated a new product rather than just recovered the starting material? Give at least two different methods to...

Suppose you want to separate a mixture of the following compounds: salicylic acid, o-cresol, p-aminoacetophenone, and napthalene. Come up with a list of steps and chemicals needed to most efficiently isolate all four compounds as solids with the greatest purity possible. You do not need to write a formal procedure, but be sure to indicate steps needed clearly and in order. In the procedure, the bicarbonate solution was acidified with HCl to precipitate out acetylsalicylic acid. Why wasn’t the water...
