Question
Chapter 21, Problem 9P
Interpretation Introduction
Interpretation
The difference between soap and sodium soap should be explained and the formula for sodium dodecyl sulfate and potassium dodecyl sulfate should be written.
Concept Introduction
Soaps are sodium or potassium salt of long chain fatty acids, produced by a process called saponification. The saponification process is one where a triglyceride and sodium or potassium hydroxide reacts to give glycerol and salt of fatty acid salt (soap). The triglycerides used in the process are mainly obtained from animal fats or vegetable oils. A hard soap is produces when sodium hydroxide is used, and soft soap is formed by use of potassium hydroxide.
