Unit 4A: Solutions, Solutes, and Factors That Affect Dissolving

Front

What is the term for a substance that dissolves in a solvent?

Back

Solute

Front

What is the term for the liquid that dissolves the solute?

Back

Solvent

Front

Why is water referred to as the 'universal solvent'?

Back

Because it can dissolve many different substances.

Front

What does it mean to dissolve?

Back

To become or cause to become incorporated into a solvent to form a solution.

Front

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

Back

A larger surface area allows a solute to dissolve faster in a solvent.

Front

What happens to the solubility of most solids as temperature increases?

Back

The solubility of most solids increases with an increase in temperature.

Front

What effect does stirring have on the dissolving process?

Back

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

Front

What is saturation in the context of solutions?

Back

Saturation occurs when a solvent can no longer dissolve any more solute at a given temperature.

Front

How does pressure affect the solubility of gases in liquids?

Back

Increasing pressure increases the solubility of gases in liquids.

Front

What is a concentrated solution?

Back

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