Unit 8 Review - Solutions

Front

What is a homogeneous mixture?

Back

A homogeneous mixture is a mixture that has a uniform composition throughout. The individual components are not distinguishable and cannot be separated by physical means.

Front

What is a heterogeneous mixture?

Back

A heterogeneous mixture is a mixture where the individual components are distinct and can be physically separated. The composition is not uniform throughout.

Front

What is a saturated solution?

Back

A saturated solution is a solution that contains the maximum amount of solute that can dissolve at a given temperature.

Front

What is a supersaturated solution?

Back

A supersaturated solution is a solution that contains more solute than can normally dissolve at a given temperature, often achieved by heating the solution and then cooling it.

Front

How do you calculate percent by mass of a solute in a solution?

Back

Front

What is the formula for calculating molarity (M)?

Back

Front

What is the definition of solute?

Back

A solute is a substance that is dissolved in a solvent to form a solution.

Front

What is the definition of solvent?

Back

A solvent is the substance in which the solute is dissolved to form a solution.

Front

What is the significance of temperature in solubility?

Back

Temperature affects solubility; generally, solubility of solids increases with temperature, while the solubility of gases decreases.

Front

What is the difference between concentrated and dilute solutions?

Back

A concentrated solution has a large amount of solute relative to the amount of solvent, while a dilute solution has a small amount of solute relative to the solvent.
