Soap dissolves the soil as such
Soap reacts with soil and converts them into soluble silicates
Soap takes away the oily part of the soil and thus separates the soil from the cloth
The soap molecules bind with the soil, lift the soil and keep it suspended which can then be rinsed away
sodium (Na)
potassium (K)
calcium (Ca)
magnesium (Mg)
Assertion : On a wet floor of a bathroom, a small circular area around a pinch of foam appears to be dry.
Reason : Soap molecules reduce surface tension and increase surface area of the thin layer of water on the wet floor.
