Understanding Solutions and Their Properties

Front

What is cohesion?

Back

The attraction between molecules of the same substance.

Front

What is adhesion?

Back

The attraction between molecules of different substances.

Front

Define a supersaturated solution.

Back

A solution that contains more solute than it can theoretically hold at a given temperature.

Front

What is the role of a solvent in a solution?

Back

It is the substance that dissolves the solute.

Front

What is a polar molecule?

Back

A molecule that has a partial positive charge on one side and a partial negative charge on the other, such as water (H2O).

Front

What is a solute?

Back

The substance that is dissolved in a solution.

Front

What is a solution?

Back

A homogeneous mixture composed of two or more substances.

Front

What is the difference between a saturated and an unsaturated solution?

Back

A saturated solution contains the maximum amount of solute that can dissolve at a given temperature, while an unsaturated solution can still dissolve more solute.

Front

What factors affect solubility?

Back

Temperature, pressure, and the nature of the solute and solvent.

Front

What is the significance of water being a polar molecule?

Back

It allows water to dissolve many ionic and polar substances, making it an excellent solvent.
