Solutions and Concentration Review

Front

What is a solution?

Back

A homogeneous mixture of two or more substances where one substance (solute) is dissolved in another (solvent).

Front

What is a solute?

Back

The substance that is dissolved in a solution.

Front

What is a solvent?

Back

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

Front

What does concentration refer to in a solution?

Back

The amount of solute present in a given quantity of solvent or solution.

Front

What is a homogeneous mixture?

Back

A mixture that has a uniform composition and appearance throughout.

Front

What is a heterogeneous mixture?

Back

A mixture that consists of visibly different substances or phases.

Front

How does heating a solution affect solubility?

Back

Heating generally increases the solubility of solids in liquids, allowing more solute to dissolve.

Front

What is molarity (M)?

Back

A measure of concentration defined as the number of moles of solute per liter of solution.

Front

What is the difference between a concentrated and a dilute solution?

Back

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

Front

What happens when you add more solute to a saturated solution?

Back

The excess solute will not dissolve and will remain undissolved.
