Solutions Review

Front

What is a solvent?

Back

A solvent is a substance that dissolves a solute, resulting in a solution. In the case of Kool-aid, water is the solvent.

Front

What is a nonelectrolyte?

Back

A nonelectrolyte is a substance that dissolves in water but does not conduct electric current.

Front

What factors affect the dissolving rate of a solid?

Back

Factors include stirring the solution, heating the solution, and increasing the surface area of the solute. Increasing pressure does not affect the dissolving rate of solids.

Front

What does it mean for a solution to be dilute?

Back

A dilute solution contains a small amount of solute relative to the amount of solvent. For example, taking medication with a full glass of water makes the solution more dilute.

Front

What is an example of a gas-liquid solution?

Back

Oxygen dissolved in water, which fish use to breathe, is an example of a gas-liquid solution.

Front

What is a solute?

Back

A solute is a substance that is dissolved in a solvent to form a solution. In Kool-aid, the Kool-aid powder and sugar are solutes.

Front

What is the difference between a concentrated and a dilute solution?

Back

A concentrated solution has a large amount of solute compared to the solvent, while a dilute solution has a small amount of solute.

Front

What is the role of temperature in dissolving solids?

Back

Increasing the temperature generally increases the rate at which a solid dissolves in a solvent.

Front

What is the significance of surface area in dissolving solids?

Back

Increasing the surface area of a solute (e.g., by crushing it) allows it to dissolve more quickly in a solvent.

Front

What is an electrolyte?

Back

An electrolyte is a substance that dissolves in water and conducts electric current.
