page 96 Exp. 12: Saponification: Preparation of a Soap Questions While many animal fats and vegetable oils contain side chains which are saturated (have only alkyl groups in the fatty acid), other oils such as olive and fish oil) have alkenes (C-C) as part of the fatty acid chain( and particularly when the double bonds are cis). These oils are much more healthy than ‘saturated, vegetable oils and animal fats since they cause less plaque build up in arteries when metabolized to the corresponding fatty acids. The following represents a typical triglyceride found in fish oil. Write a specific balanced reaction for the saponification of this fish oil 1. O-C-(CH CHHHECH(CH)s-CH 3 NaOH CH2-O-C-(CH2)r CH:CH-CH-CHaCH-(CH)-CHa H2O a typical fish oil 2. What property of soaps makes them form micelles Why do 'natural' soaps often cause eye irritation when they come in contact with your eyes? What can be done to soaps to eliminate this problem (as with most commercially available 3. soaps)?Explanation / Answer
2) soap consist of 2 parts hydrophobic and hydrophilic but the ionic salt part or The "salt" end of the soap molecule is ionic and hydrophilic (water soluble). When grease or oil (non-polar hydrocarbons) are mixed with a soap- water solution, the soap molecules work as a bridge between polar water molecules and non-polar oil molecules.
Hydrophillic property makes them form micelles.
