7.6E Rate of Dissolution

Front

What is the rate of dissolution?

Back

The rate of dissolution is the speed at which a solute dissolves in a solvent to form a solution.

Front

What factors can increase the rate of dissolution?

Back

Factors include increasing temperature, stirring the solution, and increasing the surface area of the solute.

Front

How does temperature affect the rate of dissolution?

Back

Higher temperatures generally increase the rate of dissolution because they provide more energy to the molecules, allowing them to move faster.

Front

What is a saturated solution?

Back

A saturated solution is one that has dissolved the maximum amount of solute at a given temperature.

Front

What is a concentrated solution?

Back

A concentrated solution contains a large amount of solute relative to the amount of solvent.

Front

What is a dilute solution?

Back

A dilute solution contains a small amount of solute relative to the amount of solvent.

Front

What is the difference between homogeneous and heterogeneous mixtures?

Back

Homogeneous mixtures have a uniform composition throughout, while heterogeneous mixtures have distinct, separate components.

Front

How does stirring affect the rate of dissolution?

Back

Stirring increases the rate of dissolution by distributing the solute particles throughout the solvent, allowing more interactions.

Front

What is surface area in the context of dissolution?

Back

Surface area refers to the exposed area of a solute that is available to interact with the solvent.

Front

How does surface area affect the rate of dissolution?

Back

A higher surface area (more smaller pieces) allows for faster dissolution compared to larger pieces.
