The SOLUTE is what dissolves; the SOLVENT does the dissolving. In salt water, salt is the solute and water is the solvent.
What is solutions cheat sheet?
Nearly every question here checks whether you can name the parts correctly and reason about what happens when you add more of one of them.
Key points
- The SOLUTE is what dissolves; the SOLVENT does the dissolving. In salt water, salt is the solute and water is the solvent.
- Water is called the universal solvent because its polarity dissolves so many substances.
- More solute in the same solvent = more CONCENTRATED. Adding solvent = more DILUTE.
- A SATURATED solution holds all the solute it can at that temperature; more solute just settles out.
- Heating usually increases how much solid solute a liquid can dissolve — which is why sugar dissolves faster in hot tea.
Study first
- Dissolve 5 g of salt in 100 mL of water, then add another 100 mL of water. The amount of salt is unchanged, but the solution is now half as concentrated — that is dilution.
- Keep adding sugar to iced tea until it stops disappearing: you have reached saturation at that temperature.
Commonly tested
- Say the sentence 'salt is the solute, water is the solvent' aloud. One concrete example fixes both terms permanently.
- For concentration questions, ask only: did the amount of SOLUTE change, or the amount of SOLVENT? That determines the direction every time.
Watch out for
- Reversing solute and solvent. The solvent is the one present in the greater amount and does the dissolving.
- Thinking dilution removes solute — it does not; it adds solvent and spreads the same solute further.
- Assuming a saturated solution is 'full' at every temperature; raising the temperature usually lets it hold more.
