Mixtures and Solutions: Investigation 3

Front

What is a mixture?

Back

A mixture is a combination of two or more substances where each substance retains its own properties.

Front

What is a solution?

Back

A solution is a special type of mixture where one substance (solute) is dissolved in another (solvent).

Front

What does it mean to dilute a solution?

Back

To dilute a solution means to add more solvent, which decreases the concentration of the solute.

Front

How can you tell if a solution is concentrated?

Back

A concentrated solution has a large amount of solute compared to the amount of solvent, often appearing darker or more intense in color.

Front

What is concentration?

Back

Concentration is the amount of solute present in a given volume of solvent or solution.

Front

What happens to the concentration when you add more solvent?

Back

The concentration decreases when more solvent is added, making the solution less concentrated.

Front

If you have two solutions, one with 30 grams of solute in 100 mL of water and another with 20 grams in 200 mL, which is more concentrated?

Back

The solution with 30 grams in 100 mL is more concentrated.

Front

What is the relationship between the amount of solute and the color of a solution?

Back

Generally, a solution with more solute will have a darker color, indicating higher concentration.

Front

What is a solute?

Back

A solute is the substance that is dissolved in a solution.

Front

What is a solvent?

Back

A solvent is the substance that dissolves the solute in a solution.
