Why is a soap solution a better cleansing agent than ordinary water?
Becomes it results in formation of micelles which help in cleaning action which is not possible in watre.

Sure chechi. Just wait for 5 minutes.
ya definately
Do u have the NCERT class 10 Science book? Its given in Chapter 4, ina nice manner.
srry,its not with me...
Okay, then listen. A soap molecule is a sodium or potassium salt of long chain carboxylic acids. The dirt is generally oily in nature. When soap reacts with water and dirt , the hydrophilic part becomes soluble in water, while hydrophobic end becomes soluble in hydrocarbons. A soap arranges its molecules in the form of a cluster, where ionic ends r on the edge, while hydrophobic ends r embedded in the centre. These clusters r called micelles. Soap in the form of a micelle is able to clean, since it forms a colloidal solution in water. Thus it helps to clean clothes.
and wat abt water?
Water does not form micelles, since it is purely ionic. Dirt is oily in nature, so soluble in hydrocarbons.
thank u
aiswaraya james i think u r in 10 & u hav nt read d book throughly
now in +1
