Why Some Liquids Mix and Others Don’t

Molecular Match: Liquids mix when their molecules are attracted to each other.
Polarity Power: Polar liquids like water blend with other polar liquids.
Oil vs. Water: Oil is nonpolar, so it repels water’s polar molecules.
“Like Dissolves Like”: This simple rule explains why similar liquids mix easily.
Invisible Bonds: Hydrogen bonds help water mix well with alcohols and other polar liquids.
Layer Effect: Immiscible liquids, like oil and water, form separate layers instead of mixing.
Detergent Trick: Soaps and detergents bridge polar and nonpolar worlds, helping them mix.
Everyday Example: Vinegar (polar) mixes with water, but separates from oil in salad dressing.
Temperature Factor: Heat can speed up mixing by giving molecules more energy.
Science at Work: Understanding miscibility is key in cooking, medicine, and chemical engineering.
