Solubility Explained: Why Sugar Dissolves but Oil Doesn’t

Solubility Defined: Solubility is how well a substance mixes evenly into a liquid.
Sugar Success: Sugar dissolves in water because both are polar and attract each other.
Molecule Match: Water molecules surround sugar molecules, breaking them apart.
Oil’s Problem: Oil is nonpolar, so water molecules push it away instead of pulling it in.
Like Dissolves Like: Polar liquids dissolve polar substances, and nonpolar dissolves nonpolar.
Invisible Blend: Dissolving means particles spread so evenly you can’t see them anymore.
Everyday Example: A spoon of sugar disappears in tea, but oil floats on top.
Temperature Boost: Heat helps sugar dissolve faster by speeding up molecular motion.
Limits Exist: Even sugar has a saturation point, where no more will dissolve.
Science in Action: Solubility is key in cooking, medicine, and even cleaning products.
