What is a solvent?

Back

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

What is a solute?

Back

A solute is a substance that is dissolved in a solvent to form a solution. For example, sugar is a solute in a sugar solution.

Front

What is a solution?

Back

A solution is a homogeneous mixture composed of two or more substances. It consists of a solute dissolved in a solvent.

Front

How can you make a solution more concentrated?

Back

You can make a solution more concentrated by adding more solute.

Front

What is the difference between saturated, unsaturated, and supersaturated solutions?

Back

A saturated solution contains the maximum amount of solute that can dissolve at a given temperature. An unsaturated solution can still dissolve more solute, while a supersaturated solution contains more solute than can typically dissolve at that temperature.

Front

What is an example of a common solvent?

Back

Water is the most common solvent and is often referred to as the 'universal solvent' because it can dissolve many substances.

Front

What happens when you add more solvent to a solution?

Back

Adding more solvent to a solution dilutes it, reducing the concentration of the solute.

Front

What is the role of temperature in solubility?

Back

Temperature can affect solubility; generally, increasing the temperature increases the solubility of solids in liquids.

What is a homogeneous mixture?

Back

A homogeneous mixture is a mixture that has a uniform composition throughout, such as a solution.

What is an example of a solute in a saltwater solution?

Back

In a saltwater solution, salt is the solute that dissolves in water.
