What is solubility?

• different materials placed together but keeping their own properties

• a mixture in which substances spread out evenly and will not settle

• the degree to which a material will dissolve in another substance

• the substance in a solution that has the greatest amount

• the substance in a solution that has the least amount

What does solubility refer to?

• The ability of a solvent to dissolve a solute

• The ability of a solute to dissolve in a solvent

• The maximum amount of solute that can dissolve in a solvent at a given temperature

• The rate at which a solute dissolves in a solvent

What is a saturated solution?

• A solution that can dissolve more solute

• A solution that cannot dissolve more solute at a given temperature

• A solution with no solute

• A solution that changes color when saturated

What does this solubility curve show?

• Solubility increases as temperature increases

• Solubility decreases as temperature decreases

• Solubility decreases as concentration increases

• Solubility is not affected by temperature

Which solute is least soluble at 90 ⁰C?
