Solutions — Class 12 ISC Chemistry revision notes
A 5-page visual revision sheet for Solutions, written for Class 12 ISC Chemistry. Formulas, diagrams and the traps that cost marks, laid out to be read the night before rather than the term before. Free, and it opens inside CapCompass.
What this Solutions sheet covers
- types and concentration
- types of solutions
- Ways of saying how concentrated it is
- Solubility, and the two rules that govern a gas
- Raoult's law, in its two forms
- volatile solute and solvent
- non volatile solute
- relative lowering
- vapour composition
- Henry, for comparison
- Ideal and non ideal solutions
- Azeotropes, which is where distillation stops working
- The four colligative properties
- The four, with the molar mass each one gives
- boiling point elevation
- freezing point depression
- osmotic pressure
- from osmotic pressure
- Molar mass from freezing point depression
- Which property to use, and why
- van't hoff factor
- Abnormal molar mass, and the factor that fixes it
- Putting the factor into all four
- vapour pressure
- boiling point
- freezing point
- degree of dissociation
- degree of association
- Working an abnormal molar mass question
- Why the elevation and depression happen at all
- The numbers worth carrying in
- Traps that cost marks
- Tricks that save time
How CapCompass uses this sheet
These notes are not a standalone PDF. CapCompass plans Chemistry chapter by chapter against your real exam dates and free hours, and when the plan reaches Solutions the sheet opens inside the study block itself — at the page covering the sub-topic that block is on, with the timer still running. Revision arrives at the moment the plan says revise, instead of having to be gone looking for.
