Explain the cleaning action of soap and detergents Related: Cleansing...
A soap has two parts that is -- one is the long chain of hydrocarbons, fatty acid (R) ,and the second part is the carboxylic acid group (COONa) . In both the parts Alkyl group is non- ionic in nature and carboxylic acid is ionic in nature. The hydrocarbon chain of the soap is insoluble in water but it attract dust particles , greese towards itself. Therefore, the particle of oil and greese present at the surface of dirty clothes get attached to it.
Carboxylic acid group is soluble in water and hence, does not attract oil and dust particles towards itself. The Alkyl group alongwith dust particles forms micelle alongwith foam is known as scum. Therefore , when soap is dissolved in water firstly micelle and then scum is produced due to which clothes become clean and dirt is collected at the base of the tub.

Soaps and detergents both r used as cleaning agent both have same cleaning agent but the soap fails to form lather with hard water.
when soap is dissolved in water then it forms micelle .
when the dirty cloth containing grease, oil put into the micelle formed water thn the Hydrogen carbon part(hydro phobic) of soap takes the grease, oil from it and the ionic part (hydrophilic)
dissolves this grease into water due to which water also got blackened.
