6. Soap production
When soap dissolves in water, the surface tension of water is reduced
The hydrophobic part of the soap molecules dissolve and attach to the greasy dirt on the cloth &
the hydrophilic part dissolve in water
Scrubbing and brushing the cloth will dislodge the greasy dirt from the cloth surface to form greasy droplets
These greasy droplets surrounded by soap molecules and suspended in soapy water
Soap bubbles produced by soapy water trap greasy droplets in the soapy water
When soapy water and bubbles are removed during rinsing, the greasy dirt will be removed
