Answer 2

a. Paraffin wax of the following fat/oil is unsaponifiable.

Saponification-

• The saponification value of a component defines the milligrams of potassium hydroxide required to saponify one gram of fat or oil.
• Unsaponifiables are those components that fail to form soap when treated with alkali.
• Unsaponifiables are components of an oily mixture that fail to form any kinds of soaps when mixed along with sodium hydroxide (lye) or potassium hydroxide.
• The unsaponifiable value of the component paraffin wax is approx 100, which makes it completely unsaponifiable.
• Later is the component bee wax with a value of 52, the lowest unsaponifiable value is of the olive oil. Thus, olive oil is most saponifiable.
• The fat shea butter also has a lower unsaponifiable value but more than that of olive oil.
