Cheat Sheet
- Homogeneous vs Heterogeneous -
Solutions are mixtures that are uniform at the molecular level, whereas other mixtures (like suspensions or colloids) have distinguishable phases. Remember "all solutions are mixtures, but not all mixtures are solutions" to keep this clear (IUPAC definition).
- Solvent and Solute Roles -
In any solution, the solvent is the majority component (e.g., water in saltwater) and the solute is dissolved (salt). A handy mnemonic: "Solvent serves, solute settles within." (Chemguide, University of Oxford).
- Concentration Calculations -
Key formulas include molarity (M = moles solute ÷ liters solution) and mass percent (% w/w = mass solute ÷ total mass × 100%). Practice by calculating a 1 M NaCl solution: dissolve 58.44 g NaCl into 1 L total volume.
- Solubility Influencers -
Temperature often raises the solubility of solids, while pressure mainly affects gas solubility (Henry's Law: C = kP). Use "Heat helps solids, pressure pleases gases" as a memory trick (Royal Society of Chemistry).
- Colligative Properties -
Adding nonvolatile solute particles changes boiling/freezing points: ΔT = i·K·m, where i is the van 't Hoff factor. For example, NaCl (i≈2) in water lowers freezing point more than sugar (i≈1) at the same molality.
