Simple Distillation Quiz

What is the key factor that allows the separation of two liquids in simple distillation?

• Their different viscosities

• Their different densities

• Their different boiling points

• Their different colors

What is the purpose of the condenser in the distillation apparatus?

• To heat the mixture

• To measure the temperature

• To filter impurities

• To cool the vapor back into a liquid

After separating liquid A, why is there no need to heat the mixture to 100 degrees to separate liquid B?

• Liquid B has already evaporated

• Liquid B is the only liquid left in the container

• Liquid B is not affected by heat

• Liquid B has a lower boiling point

How does the distillation process change when separating a saltwater solution?

• The method involves adding more salt

• The method requires a different apparatus

• The method uses a different type of condenser

• The method remains the same, focusing on the boiling point of water

In the example of chlorophyll in ethanol, what is the main goal of the distillation process?

• To change the color of the mixture

• To separate the chlorophyll from ethanol

• To increase the boiling point of ethanol

• To dissolve the chlorophyll completely
