Gas Solubility and Properties

What is a solution?

• A mixture where particles of a solute are dissolved in particles of a solvent.

• A substance that dissolves other substances.

• A substance that gets dissolved.

• A pure substance with only one type of molecule.

In the air we breathe, which gas acts as the solvent?

• Oxygen

• Carbon Dioxide

• Nitrogen

• Argon

Which of these is a property that affects how well a substance dissolves?

• Color

• Molecular structure

• Weight

• Smell

Why does a substance dissolve well in a solvent?

• The substance and solvent have different colors.

• The substance and solvent have similar polarities.

• The substance is very heavy.

• The solvent is very cold.

What is partial pressure?

• The total pressure of all gases in a mixture.

• The pressure caused by only one specific gas in a mixture.

• The pressure inside a soda can.

• The pressure that makes liquids boil.

Why does carbon dioxide gas rush out of a soda can when it is opened?

• The temperature of the soda suddenly increases.

• The pressure of the carbon dioxide inside the can becomes too high.

• The normal air pressure outside the can is not enough to keep the carbon dioxide dissolved.

• The soda becomes too sweet, causing the gas to escape.

What does Henry's Law help us figure out?

• How much liquid is in a container.

• How much gas is dissolved in a liquid.

• The temperature of a solution.

• The weight of a gas molecule.

How does increasing the temperature of a liquid affect the amount of gas that can dissolve in it?

• More gas can dissolve.

• Less gas can dissolve.

• The amount of dissolved gas stays the same.

• The gas turns into a solid.
