Question

1. How did the consistency of the solutions differ after the 5-minute hot water bath incubation and after allowing the solutions to sit for 1 hour?

2. Describe the differences in consistencies of the 4 soaps.

3. Assume the following: canola oil has 6% saturated fats and 94% unsaturated fats; corn oil has 13% saturated fats and 87% unsaturated fats; and coconut oil has 91% saturated fats and 9% unsaturated fats.

Describe the relationship between the consistency of each soap sample and the saturation of oil.  

Explanation / Answer

3.Describe the relationship between the consistency of each soap sample and the saturation of oil.

saponification (soap-making) reaction.

All fat molecules are synthesized from one glycerol molecule and 3 fatty acids, which are linked in an esterification reaction.Fats, also known as triglycerides or triacylglycerols, are biomolecules synthesized by the body from excess food intake.The fatty acids are long-chain hydrocarbon molecules that terminate with a carboxylic acid group. The chains contain an even number of C atoms, varying typically between 12 and 18 C atoms, and may contain one or more C=C double bonds (unsaturated), or may contain only single-bonded carbons (saturated).

Food producers often use vegetable oils in many products that they wish to have a solid-like consistency (in addition to the consistency, another benefit is greater resistance to spoilage, and hence a longer shelf life).Consequently, they often hydrogenate (or partially hydrogenate) the unsaturated fats found in these vegetable oils so that they behave more like saturated fats

Therefor saturated oil produce solid lie consistency in the soap.
