Question

How does the use of a detergent help to clean soiled clothes

Answer 1

The hydrophobic tail attaches itself to grime and dirt, while the hydrophilic head gets affixed to water molecules. Therefore, when the dirty clothes are put inside a washing machine or swished vigorously by hand, dirt is pulled away from the cloth and washed away in the water, leaving the cloth sparkling clean.

${\huge{\textsf{\textbf{Answer :}}}}$

     

❖ Detergent is a cleansing agent that combines with the impurities to make them more soluble and therefore wipe them away.

❖ A molecule of detergent consists of two ends. One of its ends is attracted towards the water while the other holds on to the dirt.

❖ This results in the mixing of dirt and water. Due to the ability to get attached to both oil and water, detergent molecule spreads easily.

❖ This property of a substance expanding on a surface is known as surface activity and the substance is known as surfactant.

❖ One of the effects of surface activity is lather formation.

❖ This action of detergent molecule results in the removal of dirt and stains from the clothes.
