Answer #1

In the vacuum filtrarion has uses a buchner funnel and side-arm flask. because vacuum filtration
is faster than the gravity filtration ,because in gravity filtration has only gravity force for the
filtration but in vacuum filtration has other forceses like as the solvent or solution and air is forced
through the filter paper by the this application is resuced pressure.
The Gravity filtration can be used to collect in the solid product, although generally vacuum
filtration is used for this purpose because it is faster.
