Chapter 15, Problem 1E
Interpretation Introduction
Interpretation:
The reason for the statement, “The stickiness of eating an orange is easily washed off hands with just plain water, whereas the greasiness of eating French fries requires soap,” is to be explained.
Concept introduction:
Soap is a water-soluble compound, which is used for washing and cleaning purpose. It is made up of natural oil or fat treated with sodium hydroxide or another strong base. In short, soaps are surfactants, that is, they are dissolved in water and oil.
Detergent is more effective than soap because it contains one or more surfactants.
