Concentrations and Solutions

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 can you make a solution more concentrated?

Back

You can make a solution more concentrated by adding more solute (like powder) to it.

Front

How can you make a solution less concentrated?

Back

You can make a solution less concentrated by adding more solvent (like water) to it.

Front

What is solute?

Back

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

Front

What is solvent?

Back

A solvent is a substance that dissolves a solute, forming a solution.

Front

What happens to the solute when it dissolves in a solvent?

Back

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

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 effect does stirring have on dissolving?

Back

Stirring increases the rate of dissolving by spreading out solute particles and increasing contact with the solvent.

Front

How does temperature affect the rate of dissolving?

Back

Higher temperatures increase the kinetic energy of molecules, leading to faster dissolving.
