level questions: Level 3
| Question | Answer |
|---|---|
| Weak electrolytes behave as | • Strong electrolytes – PH of solution in ionic form • Non-electrolytes |
| precipitation occurs | Unionic form |
| solute is more soluble in a mixture of solvents than in one solvent alone | Cosolvency |
| • Solubility increases with __ particle size | low |
| • No change in the properties of the components other than dilution • No heat is evolved or absorbed during the mixing process (no shrinkage / expansion) • Final volume of the solution represents an additive property of the individual constituents | Ideal Solution |
| • Those made up of strong dipolar molecules having hydrogen bonding | Polar solvents |
| • Those also made up of strong dipolar molecules but that do not form hydrogen bonds | Semi-polar solvents |
| • Those made up of molecules having a small or no dipolar character | Non-polar solvents |
