7.6DE Aqueous Solutions and Dissolution Extra Practice

Front

What is a solvent in an aqueous solution?

Back

A solvent is a substance that dissolves a solute, resulting in a solution. In an aqueous solution, the solvent is typically water.

Front

What is a solute?

Back

A solute is a substance that is dissolved in a solution. It is present in a lesser amount compared to the solvent.

Front

How does temperature affect the rate of dissolution of a solid solute?

Back

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

Front

What is concentration in the context of solutions?

Back

Concentration refers to the amount of solute present in a given amount of solvent.

Front

What happens to the rate of dissolution when you decrease the surface area of a solid solute?

Back

Decreasing the surface area of a solid solute generally decreases the rate of dissolution.

Front

What is an example of an aqueous solution?

Back

An example of an aqueous solution is saltwater, where salt (solute) is dissolved in water (solvent).

Front

What is the role of stirring in the dissolution process?

Back

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

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 is dilution?

Back

Dilution is the process of reducing the concentration of a solute in a solution, usually by adding more solvent.

Front

What is the effect of pressure on the solubility of gases in liquids?

Back

Increasing pressure generally increases the solubility of gases in liquids.
