Cleansing Action of Soaps and Detergents. A soap molecule consists of two parts: A long chain hydrocarbon tail. Difference between acetic acid and ehenol, What kind of hydrocarbon burns with blue flame. The mechanism of the cleansing action of soaps : When soap is at the surface of water, the hydrophobic tail protrudes out of water while the ionic end remains inside water.
The molecules of soap are sodium or potassium salts of long-chain carboxylic acids. This simulation help to compare the foaming capacity of soap with different samples of water. Detergents have better cleansing action as compared to soaps. Soaps are sodium or potassium salts of long-chain fatty acids [carboxylic acids -Stearic acid, palmitic acid or oleic acid]..
Saponification: The process in which oil or fat is hydrolysed with Sodium hydroxide to get soap and glycerol is called saponification. The ionic-end of soap dissolves in water while the carbon chain dissolves in oil. Disadvantages of detergent. For example, sodium n-dodecyl benzene sulphonate and sodium n-dodecyl sulphate or sodium lauryl sulphate. Preview this quiz on Quizizz.
Since the soap is lighter, it floats like cream on the solution. This video gives real lab experience and also provides inference at each step. You can see some Soaps and Detergents Class 10 Notes EduRev sample questions with examples at the bottom of this page. Practically, however, the soap industry is concerned mainly with those water-soluble soaps that result from the interaction between fatty acids and alkali metals.
Advantages of syntbeti. When the soap cools and solidifies, it is cut out into desired shapes and packed. Glycerol, which exists in a dissolved state in the solution, is separated with the help of distillation. The various micelles present in water do not come together to form a precipitate as each micelle repels the other because of the ion-ion repulsion.

Eggsperiments Fun with Flour Celery Rocks! Soaps and detergents are made from long molecules that contain a head and tail. These molecules are called surfactants ; the diagram below represents a surfactant molecule. The head of the molecule is attracted to water hydrophilic and the tail is attracted to grease and dirt hydrophobic.
Soap is a salt of a fatty acid  used in a variety of cleansing and lubricating products. In a domestic setting, soaps are surfactants usually used for washing , bathing , and other types of housekeeping. In industrial settings, soaps are used as thickeners , components of some lubricants , and precursors to catalysts. When used for cleaning, soap solubilizes particles and grime, which can then be separated from the article being cleaned.
