Solubility and Solutions

Concentration can be defined as...

• the volume of the solvent.

• the mass of the solute.

• a saturated solution which contains the maximum amount of solute.

• the amount of solute in a given amount of solvent.

Solubility is defined as...

• the ability of a solvent to dissolve.

• the maximum amount of solute that will dissolve in a given amount of solvent at a given temperature.

• the ability to form a precipitate.

• the ability to increase the volume of a solution based on an increase in temperature.

The substance being dissolved in a solution.

• sands
• solute
• solvent
• alloy

The substance in which a solute is dissolved

• sands
• solvent
• alloy
• negative particles

As concentration increases, density...

• decreases

• increases

• stays the same

When a solvent contains as much of the solute as it can hold, the solution is said to be

• supersaturated
• diluted
• saturated
• unsaturated

How does a solution become supersaturated?

• Add more solvent to the existing solution.

• Increase the temperature of the solution and stir it.

• Dissolve more solute in the solution than you should be able to at a specific temperature.

• Add extra solvent and dissolve more solute until it is saturated.

What substance is known as the universal solvent?

• Salt

• Vinegar

• Water

• Hydrogen peroxide

What does it mean to dilute a solution?

• lower the concentration of solute per solvent
• increase the concentration of solute per solvent

You can make a solution more concentrated by adding __________.

• solute
• solvent
• water
