Mixture and Separation Techniques

What is the process of separating insoluble solid particles from a liquid by passing the mixture through a filter?

• Filtration

• Distillation

• Evaporation

• Condensation

Which separation technique is used to separate a solvent from a solution by heating the solution until the solvent evaporates and then condenses into a separate container?

• Decantation

• Distillation

• Chromatography

• Filtration

What is the process of separating the components of a liquid mixture by boiling and then condensing the vapor into a separate container?

• Filtration

• Distillation

• Evaporation

• Combustion

Which separation technique involves the separation of a mixture by passing it in solution or suspension through a medium in which the components move at different rates?

• Distillation

• Evaporation

• Filtration

• Chromatography

What is the purpose of filtration in separation techniques?

• To mix solid particles with a liquid or gas

• To separate solid particles from a liquid or gas

• To increase the concentration of solid particles in a liquid or gas

• To decrease the viscosity of a liquid or gas

How does evaporation help in the separation of mixtures?

• Volatile component vaporizes and leaves the non-volatile component behind

• The non-volatile component vaporizes and leaves the volatile component behind

• Evaporation causes the components to mix further

• Evaporation has no effect on the separation of mixtures

What is the main difference between simple distillation and fractional distillation?

• Simple distillation uses a fractionating column

• Simple distillation is used for separating mixtures with similar boiling points

• Simple distillation is more accurate than fractional distillation

• Fractional distillation allows for the separation of liquids with closer boiling points.

What is the purpose of chromatography in separation techniques?

• To create new substances

• To separate and analyze mixtures of substances based on their different affinities for a stationary phase and a mobile phase.

• To determine the color of a mixture

• To measure the volume of a liquid

What are the different types of chromatography techniques?

• Column chromatography, flash chromatography, preparative chromatography, and analytical chromatography

• High-performance liquid chromatography, supercritical fluid chromatography, affinity chromatography, and ion-exchange chromatography

• Gas chromatography, liquid chromatography, thin-layer chromatography, and paper chromatography

• Solid chromatography, gel chromatography, vapor chromatography, and foam chromatography

Explain the principle behind the separation technique of distillation in the context of purifying water.

• Different substances have different boiling points

• Distillation is based on the principle of color differences

• Different substances have the same boiling points

• Distillation works by using a magnet to separate substances
