Which fat sample will require more KOH for complete saponification cottonseed oil or the same mass of lard?
The lard sample will require more KOH for complete saponification. This is because lard is a saturated fat, and therefore the molecules are more closely packed together. This means that there are more bonds that need to be broken in order to saponify the fat.
Why is the hydrolysis of fat called saponification?
The term "Saponification" is an indication of what this reaction originally was used for: making soap. By boiling animal fat or lard with either potassium hydroxide or sodium hydroxide, the reaction, hydrolysis, produced glycerol and soap.
