Cleansing Action Of Soap and Detergent

•Soap ionises in water to produce free moving soap anions and cations.

•Soap anions reduces the surface tension of water that increase wetting ability of water.

•Hydrophilic part of soap anions remains the same in water and hydrophobic part dissolves and penetrates into the grease.

•By the movement of water during the scrubbing and rubbing, grease is loosened and lifted off the surface.

•The hydrophobic part of soap anions surround the grease, the grease is suspended in the water

•The grease is dispersed into smaller droplet

•The small droplets do not redeposit on the surface of cloth due to repulsion between negative charges

•The droplet are suspended in water, forming an emulsion

•Rinsing away the dirty water removes the grease droplets and the surface of the cloth is then cleaned

What Is Chemistry All About?

C h e m i s t r y !

Chemistry is study of :

• nature,
• properties, and
• composition of matter, and
• how these undergo changes.

Chemistry is concerned with atoms and their interactions with other atoms.

Chemistry is sometimes called "the central science".

Do you know why Chemistry called as " the central science"?

It is because Chemistry connects physics with other natural sciences such as geology and biology.
