Solubility Curves

What is the definition of "solubility?"

• max amount of solvent that is dissolved in a solute

• max amount of solute that is dissolved in a solvent

• max amount of sugar dissolved in water

• minimum amount of a solute that is dissolved in water

Knowing the solubility of a substance can help you

• classify solutions.

• identify unknown substances.

• classify reactants in solutions.

• identify both reactants & products in solutions.

Depending on the amount of solute in a solution, solutions can be described as

• saturated or unsaturated.

• supersaturated.

• a solvent or a solute.

• sugar or water.

A _____ solution contains ______ solute than it can normally hold at a given temperature.

• saturated, less

• saturated, more

• supersaturated, less

• supersaturated, more

A _____ solution contains as much _____ as the solvent can hold at a given temperature.

• supersaturated, solute

• saturated, solute

• unsaturated, solute

• unsaturated, solvent

A solution that has ____ than the maximum amount of solute is a(n) _____ solution.

• more, saturated

• less, saturated

• less, unsaturated

• more, unsaturated

Supersaturated solutions can hold more solute than normal because

• the solute can dissolve less.

• the solute can dissolve at a faster rate.

• the solvent can be heated.

• the solvent can be supercooled.

Supersaturated solutions can be very ____ once cooled.

• stable

• unstable

• fragile

• fluid

If you add a spoonful of sugar to your ice tea & it dissolves, then you know that the solution

• is saturated.

• is supersaturated.

• is unsaturated.

• can hold more solute.

Solutes can easily precipitate out of a ____ solution if the solution is disturbed.

• saturated

• supersaturated

• unsaturated

• polar
