Recommended Placement in the Curriculum We used the Fatty Acids for Soap …3.6: Application of Solubility: Soap - Chemistry LibreTextsOne of these is caused by the weak acidity (pK a ca. 4.9) of the fatty acids. Solutions of alkali metal soaps are slightly alkaline (pH 8 to 9) due to hydrolysis. If the pH of a soap solution is lowered by acidic contaminants, insoluble fatty acids precipitate and form a scum.

Soap - Elmhurst University

Soap is a mixture of sodium salts of various naturally occurring fatty acids. Air bubbles added to a molten soap will decrease the density of the soap and thus it will float on water. If the fatty acid salt has potassium rather than sodium, a softer lather is the result. Soap is produced by a saponification or basic hydrolysis reaction of a fat ...

Soap, from a chemical standpoint, is a salt (or a mixture of salts) of fatty acids. As with all salts, soap contains a positive ion, usually Na+ or K+, and a negative ion, usually the anions of long-chained carboxylic acids obtained by the hydrolysis of animal or vegetable fats. These fatty

Fatty acids that are saturated, containing no double bonds, are straight

Estimation of Saponification Value of Fats/Oils. (Theory ...

Fats and oils are the principle stored forms of energy in many organisms. They are highly reduced compounds and are derivatives of fatty acids. Fatty acids are carboxylic acids with hydrocarbon chains of 4 to 36 carbons, they can be saturated or unsaturated. The simplest lipids constructed from fatty acids are triacylglycerols or triglycerides.
