Soaps and detergents
In this Class 10 Science topic from the chapter Carbon and its Compounds, students learn how soaps and detergents remove dirt and oil. They explore the structure of soap as sodium or potassium salts of long-chain fatty acids, and understand how the hydrophobic and hydrophilic ends of their molecules form micelles in water. The topic also explains saponification, the difference between soaps and synthetic detergents, and why soaps are less effective in hard water because they form scum with calcium and magnesium ions.
