1) Esters of fatty acids with glycerol are important in nature. Give a structural formula examplel and elaborate on their importance.
2) The fatty acid esters of glycerol in #1 undergo SAPONIFICATION when treated with aqueous NaOH to form soap. From the structure of fatty acid esters of glycerol that you wrote earlier, write the structure of the corresponding soap.
Suppose that a student performing this experiment recorded the concentration of NaOH solution as 0.513 M, instead of the correct value of 0.531 M.
Why is molarity not the best means of stating acid strength? Is molarity the most representative form of quantifying acids and bases?
