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 affect the rate of dissolution?

Back

Factors include temperature, agitation (stirring), surface area of the solute, and the nature of the solute and solvent.

Front

How does temperature affect the rate of dissolution?

Back

Higher temperatures generally increase the rate of dissolution because particles move faster and collide more often.

Front

What is agitation in the context of dissolution?

Back

Agitation refers to stirring or shaking a solution to help mix the solute and solvent, increasing the rate of dissolution.

Front

Why does stirring increase the rate of dissolution?

Back

Stirring helps distribute the solute particles throughout the solvent, allowing more collisions and faster dissolution.

Front

What is surface area in relation to solutes?

Back

Surface area refers to the exposed area of a solute that is available to interact with the solvent; greater surface area leads to faster dissolution.

Front

What is a concentrated solution?

Back

A concentrated solution has a high amount of solute relative to the amount of solvent.

Front

What is a saturated solution?

Back

A saturated solution is one in which no more solute can dissolve at a given temperature and pressure.

Front

What is an unsaturated solution?

Back

An unsaturated solution is one that can still dissolve more solute at a given temperature and pressure.

Front

What is a diluted solution?

Back

A diluted solution has a low amount of solute relative to the amount of solvent.
