When using vacuum filtration to separate a dissolved solid from an undissolved solid, what techniques should you use to ensure a quantitative separation

See explanation

Explanation:

Vacuum filtration is referred to as a fast filtration technique that is used in the separation of solids from liquids. It is also used to collect a desired solid. It basically uses a side-arm flask and a Buchner funnel.

Based on the question, the techniques that should be used to ensure a quantitative separation goes thus:

• Wet the filter paper before the mixture is poured into the filter funnel.

• Then, carefully rinse the flask with a little amount of water into the filter funnel.

• After that, the solid on the filter paper should be washed the with a small amount of water.

• Finally, Dry the solid on the filter paper when the separation is done.
