give cleaning action of soap and advantages of detergent over them
Answers
Hey Mate..
When soap is dissolved in water, its hydrophobic ends attach themselves to dirt and remove it from the cloth.
First, the molecules of soap arrange themselves in micelle formation and trap the dirt at the centre of the cluster.
These micelles remain suspended in water like particles in a colloidal solution.
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.
Thus, the dust particles remain trapped in micelles (which remain suspended) and are easily rinsed away with water.
Hence, soap micelles remove dirt by dissolving it in water.
Advantages of detergents over soaps :
-Detergent cleans more effectively in hard water than soap. Hard water contains calcium and magnesium ions that limit soap's cleaning capabilities. When combined with soap, hard water develops a type of film that leaves a deposit on clothes or skin that does not easily rinse away. Over time, this can lead to the deterioration of the fabric and eventually ruin the clothes. On the other hand, detergents are made with chemicals that are not affected by hard water.
