Chem: Common Laboratory Techniques

It is usual method for group separations

• Filtration

• Centrifugation

• Precipitation

• Evaporation

The sedimentation of particles under the influence of the centrifugal force and it is used for separation of superfine suspensions

• Filtration

• Centrifugation

• Precipitation

• Evaporation

Used to reduce the volume of the solution

• Filtration

• Centrifugation

• Precipitation

• Evaporation

The act of pouring a mixture onto the membrane that allows a passage of liquid and results in the collection of solid

• Filtration

• Centrifugation

• Precipitation

• Evaporation

A device by which a centrifugal force produced an electric motor speeds up the rate of settling of a precipitate

• Funnel

• Evaporating Dish

• Centrifuge

Uses glass funnel with a stem and filter paper folded using basic technique or fluted type

• Distillation

• Gravity Filtration

• Decantation

• Chromatography

It involves distribution of a solute in two immiscible solvents

• Filtration

• Evaporation

• Sublimation

• Extraction

A process in which the components of the mixtures are separated by pouring out liquid so as not to disturb the solids that readily settle at the bottom of the container

• Distillation

• Gravity Filtarion

• Decantation

• Chromatography

A process in which the solid of highly vapor pressure passes directly to the gaseous state without passing through the liquid state

• Filtration

• Evaporation

• Sublimation

• Extraction

A process of separating liquid mixtures with the components of varying degrees of volatility or significant differences in boiling point

• Distillation

• Gravity Filtration

• Decantation

• Chromatography
