7.6DE Aqueous Solutions and Dissolution Extra Practice

Front

What is dissolution?

Back

Dissolution is the process by which a solute dissolves in a solvent to form a solution.

Front

What is a solute?

Back

A solute is the substance that is dissolved in a solution.

Front

What is a solvent?

Back

A solvent is the substance that dissolves the solute, typically a liquid.

Front

How does temperature affect the rate of dissolution?

Back

Increasing the temperature generally increases the rate of dissolution of a solid solute.

Front

What effect does stirring have on the rate of dissolution?

Back

Stirring increases the rate of dissolution by distributing the solute particles throughout the solvent.

Front

What happens to the concentration of a solution when more solute is added?

Back

The concentration of the solution increases when more solute is added.

Front

What happens to the concentration of a solution when more solvent is added?

Back

The concentration of the solution decreases when more solvent is added.

Front

What is the relationship between surface area and rate of dissolution?

Back

Increasing the surface area of a solid solute increases the rate of dissolution.

Front

What is saturation in a solution?

Back

Saturation occurs when a solution can no longer dissolve additional solute at a given temperature.

Front

What is a concentrated solution?

Back

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