Solubility Flashcards
What happens when a hot concentrated solution of a salt is cooled?
When a hot concentrated solution of a salt is cooled some of the solute will be deposited. This is because the solubility of a solid decreases when the temperature decreases and some of the solid will crystallise out and be deposited.
What is the the definition of a saturated solution?
A solution in which no more solute will dissolve at a particular temperature.
What is the definition of solubility?
Mass of solute in grams required to saturate 100g of a solvent at a particular temperature.
How does a person calculate the mass of solute deposited when the solution has cooled?
To calculate the mass of solid deposited fine out the difference between the solubility values at each temperature.
