Study Notes
Solubility Concepts
- At 50℃, a solution with 12g of potassium dichromate (K₂Cr₂O₇) per 100g of water is not saturated; an additional 18g is needed to reach saturation.
- Not all substances exhibit increased solubility with rising temperature; this statement is false regarding solubility curves.
Measuring Solubility
- Solubility is quantified by the maximum mass of a solute that can dissolve in 100g of solvent at a specified temperature.
Creating Supersaturated Solutions
- Supersaturation occurs by first creating a saturated solution, then heating it, adding extra solute, and finally cooling back down.
Characteristics of Supersaturated Solutions
- A supersaturated solution holds more dissolved solute than what is typically possible for a saturated solution under equivalent conditions.
