Chromatography and Fractional Distillation Quiz

What is the principle of fractional distillation?

• Separation of liquids with different boiling points

• Heating a single liquid to its boiling point

• Mixing liquids to form a new substance

• Adding chemicals to separate liquids

How is chromatography used in daily life?

• It is used for cooking food

• It is used for separating and analyzing different components in various samples.

• It is used for watering plants

• It is used for fixing electronic devices

What is the purpose of fractional distillation?

• To separate a mixture of liquids with different boiling points.

• To prevent the separation of liquids

• To combine liquids with similar boiling points

• To create a mixture of liquids with different boiling points

Give an example of how chromatography is used in the food industry.

• To test the temperature of food during transportation

• To measure the acidity of food products

• To analyze and separate food components

• To determine the expiration date of food items

What are the key components required for fractional distillation?

• Distillation flask, fractionating column, condenser, collection beaker

• Filter paper, funnel, evaporating dish, stirring rod

• Eureka can, measuring cylinder, weight

• Bunsen burner, beaker, test tube, pipette

Explain the concept of stationary phase in chromatography.

• The stationary phase is the phase that evaporates during chromatography.

• • the stationary phase is contained on the paper and does not move through it

• The stationary phase is the phase that moves the fastest during chromatography.

• The stationary phase is the phase that changes color during chromatography.

How does fractional distillation separate different components of a mixture?

• Based on their boiling points

• Based on their color

• Based on their density

• Based on their solubility
