True or False Flashcard

Front

What is solubility?

Back

Solubility is the ability of a substance (solute) to dissolve in a solvent, forming a solution.

Front

Does stirring a solution increase its solubility?

Back

True. Stirring helps distribute the solute particles, allowing them to interact more with the solvent.

Front

What happens to the surface area of a sugar cube when it is broken down into a powder?

Back

The surface area increases, allowing it to dissolve faster.

Front

In a solution, what is the solvent?

Back

The solvent is the substance that dissolves the solute; in Kool-aid, water is the solvent.

Front

Is wood soluble in water?

Back

False. Wood does not dissolve in water; it is considered insoluble.

Front

How does temperature affect the solubility of most substances?

Back

Most substances become more soluble as the temperature increases.

Front

What is a solute?

Back

A solute is a substance that is dissolved in a solvent to form a solution.

Front

What is an example of an insoluble substance?

Back

Sand is an example of an insoluble substance in water.

Front

What is the difference between a solution and a mixture?

Back

A solution is a homogeneous mixture where the solute is completely dissolved in the solvent, while a mixture can be heterogeneous.

Front

What is the role of temperature in dissolving sugar in water?

Back

Higher temperatures increase the kinetic energy of molecules, helping sugar dissolve faster.
