Mid Term Review Pt. 1 Chemistry

How would a solute affect the boiling point of water? 

• The boiling point of the solution will be the same as the freezing point of the solution
• the solution will boil at a lower temperature than pure water
• The solution will not boil
• the solution will boil at a higher temperature than pure water

What is one way to increase solubility of sugar in water?

• Decrease the amount of water
• Increase the amount of sugar
• chill the water
• heat the water

How is a solute different from a solvent in a solution?

• The solute is a liquid and the solvent is a gas
• the solute is present in a smaller amount
• the solute is a solid and the solvent is a liquid
• the solute is present in a greater amount

In a water solution, how do acids differ from bases? 

• acids form hydrogen ions (H+), while bases form hydroxide ions (OH-)
• Hydrogen ions (H+) remain dissolved, but hydroxide ions (OH-) do not
• acids turn litmus blue, while bases turn litmus red
• acids form salts, but bases do not
