Solutions Part 1

In a solution of salt water, what is the solvent?

• salt

• water

What does "miscible" mean?

• Dissolves in water

• Does not dissolve in water

• Two liquids that mix with each other

• A solution made of two solids

What type of compound is water?

• Ionic

• Metallic

• Polar covalent

• Nonpolar covalent

What is solubility?

• The amount of solvent that can dissolve in a solute

• The max amount of solute that can be dissolved in a solvent

• The temperature at which a solute dissolves

• The rate at which a solvent evaporates

Which factor does NOT affect the rate at which a substance dissolves?

• Changing the temperature

• Stirring or agitating the solute

• Particle size

• Mass of the solute

What happens when you crush a solute into smaller particles?

• It dissolves slower

• It dissolves faster

• It changes color

• It becomes insoluble

What usually happens to the solubility of solids in water as the temperature increases?

• It decreases

• It remains the same

• It increases

• It fluctuates
