Understanding Solutions Quiz

What is a solution?

• A mixture of two or more substances that cannot be separated by filtration

• A type of chemical reaction

• A solid object

• A type of energy

What is the solute in a sugar water solution?

• Water

• Sugar

• Salt

• Air

What does the concentration of a solution describe?

• The color of the solution

• The temperature of the solution

• The amount of solute compared to the amount of solvent

• The amount of solvent compared to the amount of solute

If you add more solute to a solution, what happens to the concentration?

• It decreases

• It stays the same

• It increases

• It becomes water

What is the solvent in a saltwater solution?

• Salt

• Water

• Sugar

• Air

If you have a solution with a small amount of solute and a large amount of solvent, how would you describe the solution?

• Concentrated

• Diluted

• Saturated

• Supersaturated

What does it mean if a solution is saturated?

• It can dissolve more solute

• It cannot dissolve more solute at a given temperature

• It has no solute

• It is only made of solvent

How can you increase the solubility of a solid solute in water?

• Decrease the temperature

• Increase the temperature

• Remove the solute

• Add more solvent

What unit is often used to express the concentration of a solution?

• Celsius

• Liters

• Grams

• Molarity

If you have two solutions, one with 10 grams of salt dissolved in 100 grams of water and another with 20 grams of salt in 200 grams of water, which solution is more concentrated?

• The first solution

• The second solution

• Both are equally concentrated

• It is impossible to determine
