Detergents are added to water for removing dirt from clothes. Explain.
(N/A) When detergents are added to water,the surface tension of the water decreases,which allows the water to wet the clothes more effectively. Detergent molecules are hairpin-shaped,consisting of a hydrophilic head and a hydrophobic tail. The hydrophobic tails attach to the dirt (oil/grease),while the hydrophilic heads remain in the water. This process helps to emulsify the dirt,lifting it away from the fabric surface and allowing it to be washed away easily.
