Mixtures & Solutions: Investigation 3/4 Review

Solution A has 100 mL of water and 10 grams of a solid. Solution B has 100 mL of water and 16 grams of a solid. Which solution is more concentrated?

• A

• B

• What does mL stand for?

• oh, I know, milliliter

Solution A has 50 mL of water and a solid. Solution B has 100 mL of water and a solid. How can you use a balance to tell with solution is more concentrated?

• just put them both on the balance. The heavier one is more concentrated.

• Pull out 50 mL from Solution B then put them both on the balance.

When layering liquids , which liquid would be on top?

• Honey = 68 g

• baby oil = 41 g

• Water = 50 g

How can you make a solution with 50 mL of water and a solute more concentrated?

• add more solvent

• add more solute

• tell the solution to concentrate on getting stronger

What happens when a solid dissolves in a container of water?

• the particles are blended throughout the water

• the soild clumps together and sink to the bottom of the container

• the solid floats to the top of the container

Solution A is heavier than solution B, but they both have the same amount of water. Why is solution A heavier?

• solution A has more solute

• they both have the same amount of solute

• solution B has more solute

Finish this sentence:

the greater the concentration, the greater the _____

• mass

• volume

Name one way to separate a solution.

• evaporate the water

• run the solution through a filter

True or False. When you pour a solution through a filter the solute separates from the water (solvent).

• that is a true fact. That is the truest statement I have ever seen.

• absolutely not! That is a complete falsehood! no way!!!

What is a diluted solution?

• a weak solution

• a strong solution
