compare concentration

Concentration is

• the amount of solute in the solvent

• the amount of solvent in the solute

• density

• particle size

What are the parts of a solution?

• water and salt

• solution and solute

• solvent and solute

• water and powder

How do you increase the concentration of a solution?

• Add more powder or solute

• Add more water

• Less powder or solute

• Less water or solvent

How do you decrease the concentration of a solution?

• Add more powder or solute

• Add more water or solvent

• Less powder or solute

• Less water or solvent

What is the term we use when we have a less concentrated solution?

• dilute

• solvent

• concentrated

• volume

What is the term we use when we have a less concentrated solution?

• dilute

• solvent

• concentrated

• volume

A solution that can hold more solute  is called

• saturated
• supersaturated
• unsaturated
• insoluble

The more solute you use, the more concentrated the solution is

• False
• Sometimes true
• Depends on the temperature
• True

To dilute something means to

• make it less concentrated or strong by adding something else
• keep it at the same concentration without adding anything else
• make it more concentrated by removing something else
• make it more diluted by adding something else

Which solution is more concentrated?

Solution 1:

500 mL of water

100 g of salt

Solution 2:

500 mL of water

90 g of salt

• Solution 1

• Solution 2

• They have the same concentration

• I have no idea
