Key Points: Soaps and Detergents

Soap molecules form micelles to trap and remove oily dirt.
Micelles have hydrophobic tails (oil-loving) and hydrophilic heads (water-loving).
Soap is less effective in hard water due to scum formation with Ca²⁺/Mg²⁺.
Detergents do not form scum and work well in both hard and soft water.
Soap and detergent solutions appear cloudy due to suspended micelles.
