SEDIMENTATION,DECANTATION,FILTRATION

Which technique is shown the diagram below

• seiving
• filtration
• decanting
• crystallization

How can we separate an insoluble solid from a liquid?

• chromatography
• crystallisation
• filtration
• condensation

What word describes the clear liquid that comes through the filter paper?

• residue
• water
• solution
• filtrate

Filtration can separate a mixture because,,,

• the parts of the mixture have different density so they separate.
• some parts of the mixture are small enough to pass through the small holes in the filter paper and some don't.
• some of the particles in the mixture are attracted to the filter paper so it stays behind.
• some parts of the mixture boil faster than others so they evaporate first.

Solid particles which are left on filter paper while filtration is called

• filtrate
• residue
• solvent
• solute

Which one of the following solids is insoluble in water?

• sugar
• sand
• copper sulfate
• salt

The particles that are settle down in sedimentation are called as

• sediments

• residue

• filtrate

—The process of separation of insoluble solids from their solutions using a filter is called

• decantation

• sedimentation

• filtration.

—The process of pouring the clear liquid after sedimentation without disturbing the sediment is called as

• filtration

• distillation

• decantation.
