DISSOLVING MATTER

Front

What is dissolving?

Back

Dissolving is the process where a substance (solute) mixes with a liquid (solvent) to form a solution.

Front

What is a solute?

Back

A solute is a substance that is dissolved in a solution, such as salt or sugar in water.

Front

What is a solvent?

Back

A solvent is a liquid that dissolves a solute, forming a solution, like water.

Front

What happens to the particles of a solute when it dissolves?

Back

The particles of the solute break apart and spread out evenly among the particles of the solvent.

Front

Does temperature affect the rate of dissolving?

Back

Yes, higher temperatures usually increase the rate at which a solute dissolves.

Front

What is saturation in a solution?

Back

Saturation occurs when no more solute can dissolve in the solvent at a given temperature.

Front

What is a concentrated solution?

Back

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

Front

What is a dilute solution?

Back

A dilute solution has a small amount of solute compared to the amount of solvent.

Front

How does stirring affect dissolving?

Back

Stirring helps to distribute the solute particles throughout the solvent, speeding up the dissolving process.

Front

What is the effect of particle size on dissolving?

Back

Smaller particles dissolve faster than larger particles because they have a greater surface area.
