Solubility Review

Look at the recipe above. Fill out the table to describe the solvent(s) and solute(s) for the lemonade, which is an aqueous solution.

• Salt

• Sugar

• Vinegar

• Water

• Lemon Juice

Suppose you want to make the lemonade sweeter. How would you change the concentration of the solution?

• Add more sugar

• Add more water

• Add more lemon juice

• Add ice cubes

What is the quickest way to dissolve salt in water?

• Increasing the temperature

• Decreasing the surface area of the solute

• Agitating the solution

• Cooling the solution

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

Concentration is

• the amount of solute in the solvent

• the amount of solvent in the solute

• density

• particle size

A mixture with more solute dissolved in the solvent than is usually soluble is called:

• concentrated

• supersaturated

• saturated

• unsaturated

The amount of solute actually dissolved in a given amount of solvent.

• dilution
• concentration
• saturated solution
• supersaturated mixture

Besides stirring, which of the following should be done to make this powder dissolve faster in the liquid?

• Add heat to the liquid

• Cool the liquid in a freezer

• Add more powder to the liquid

• Store the mixture in a dark place

A student is preparing solutions for a laboratory experiment by dissolving solid solutes in liquid solvents. Which action will increase the rate of solubility

• lowering the temperature of the solvent

• stirring the solute in the solution

• increasing the pressure on the solution

• increasing the particle size of the solute
