Class 10 Science - Chapter Carbon and Its Compound NCERT Solutions | People use a variety of methods to wash
People use a variety of methods to wash clothes. Usually after adding the soap, they ‘beat’ the clothes on a stone, or beat it with a paddle, scrub with a brush or the mixture is agitated in a washing machine. Why is agitation necessary to get clean clothes?
A soap molecule has two parts: hydrophobic head and hydrophilic tail. With the help of these, it attaches to the grease or dirt particle with the hydrophobic end of the soap molecule and forms a cluster around dirt called micelles. These micelles remain suspended as a colloid. To break these micelles (entrapping the dirt), it is necessary to agitate clothes.
