Question

After assembling a gravity filtration apparatus, begin the separation of a mixture by (choices: decanting, pouring, dumping) it into the filter paper. Pour the entire contents of the mixture into the filter paper, (choices: drying, removing, stirring) the solid in the filter paper if needed to speed up the filtration. After all the liquid has drained through the filter paper, finish by rinsing the solid with (choices: water, acetone, solvent)

After a mixture has been poured through filter paper, the (choices: liquid solid) component remains on top while the (choices: liquid, solid) flows through. To collect the solid, spread the filter paper (choices: in a flask, on a watch glass) and allow the solvent to (choices: evaporate, condense)

Once the vacuum filtration set-up is complete, start by (choices: scratching the filter paper adding a small amount of water, folding the filter paper) in the filter funnel. Then, (choices: quickly dump, shake, slowly decant) the mixture (choices: down the side of the filter funnel, near the edge of the filter paper, into the middle of the filter paper)

Answer 1

In a gravity filtration apparatus, you pour the mixture into the filter paper, remove excess solid to facilitate filtration, and rinse the solid with water. The solid remains on the filter paper while the liquid passes through, which is then allowed to evaporate on a watch glass. When using vacuum filtration, fold the filter paper in the funnel and slowly decant the mixture into the middle of the filter paper.

Understanding Filtration in Chemistry

After assembling a gravity filtration apparatus, begin the separation of a mixture by pouring it into the filter paper. Pour the entire contents of the mixture into the filter paper, removing the solid in the filter paper if needed to speed up the filtration. After all the liquid has drained through the filter paper, finish by rinsing the solid with water.

After a mixture has been poured through filter paper, the solid component remains on top while the liquid flows through. To collect the solid, spread the filter paper on a watch glass and allow the solvent to evaporate. Once the vacuum filtration set-up is complete, start by folding the filter paper in the filter funnel. Then, slowly decant the mixture into the middle of the filter paper.
