When No More Solute Dissolves the Solution Is

How does a solution become supersaturated?

• dissolve lots of solute in it.

• dissolve a little solute in it. 

• dissolve more solute than you should be able to. 

• dissolve a solvent in it.

A mixture with more solute dissolved in the solvent than is usually soluble is called:

• concentrated

• supersaturated

• saturated

• unsaturated

The amount of solute that can be dissolved in a specific amount of solvent at a given temperature is its

• concentration.

• density.

• dilution.

• solubility.

A ___________ is the mixture formed when solutes dissolves in a solvent.

• solution

• solvent

• liquid

• solid

A solution that contains all of the solute it can hold at a given temperature is

• diluted.

• saturated.

• supersaturated.

• unsaturated.

A technican prepared a solution by heating 100 mL of distilled water while adding KCl crystals until no more KCl would dissolve. She then capped the clear solution and set it aside on the lab counter. After several hours she noticed the solution had become cloudly and some solid had settled to the bottom of the flask. Which statement best describes what happened?

• As the solution cooled, evaporation of water increased the KCl concentration beyond its solubility.

• Water molecules, trapped with the KCl crystals, were released after heating.

• At lower temperatures the solubility of KCl decreased and recrystallization occurred.

• At increased temperatures the solubility of KCl increased and remained too high after cooling.

A solution that is able to dissolve additional solute is best described as

• supersaturated.

• concentrated.

• saturated

• unsaturated.

The ability of a solute to be dissolved is called its

• nature

• mixture

• solubility

• solvent

When no more solute dissolves in a solution, the solution is said to be:

• C) Supersaturated

• D) Diluted

Which of the following best describes a saturated solution?

• A) A solution that can dissolve more solute at a given temperature

• B) A solution that has dissolved all the solute it can at a given temperature

• C) A solution with more solute than solvent

• D) A solution that is clear and colorless
