Solution Practice

The solubility of a gas decreases as

• the pressure increase
• the temperature increases
• the temperature decreases
• the solvent is less polar

A solid solute contact with solvent is enhanced by all of the following except

• increasing surface area
• stirring
• crushing the solute
• increasing pressure

The role of water in aqueous solution formation is to

• hydrate solute particles
• form ionic bonds with solute
• be surrounded by solute molecules
• react with solute molecules

Molarity allows us to calculate directly the following

• freezing point depression
• number of particles in solution
• percent hydration
• partial pressure

One of the following is not affected by temperature

• molarity values
• gas solubility
• molality values
• solid solute solubility

Boiling point is a __________ property of water

• collective
• collaborative
• colligative
• collegial

The boiling point of a liquid is raised by

• increasing the number of solute particles
• increase in pressure
• decreasing the number of solute particles
• using nonelectrolytes instead of electrolytes

The symbol (s) stands for

• solid
• solute
• solvent
• solution

All alkali metal salts are
