When you dissolve sugar in water to make lemonade, you are creating a Solution. In Class 9 Chemistry (Is Matter Around Us Pure?), understanding the two components of a solution — the Solute and the Solvent — is the first step.
Water is called the Universal Solvent because it can dissolve more substances than any other liquid on Earth!
Solution = Solute + Solvent
When salt is dissolved in water → Salt is the solute, Water is the solvent, and the resulting salt water is the solution.
Solutions are not just liquid! Based on the state of solute and solvent:
Yes. When two liquids dissolve in each other (like ethanol and water), the one present in *larger* quantity is the solvent.
Why do Ionic Compounds have High Melting Points?
Get the perfect board exam answer explaining why ionic compounds like NaCl have incredibly high melting points due to strong electrostatic forces of attraction.
