Allow the solid to settle to the bottom of the flask. Decant (carefully pour) the liquid into the center of the funnel, being careful not to let the level of liquid rise above the top edge of the filter paper. By initially transferring only the liquid portion of the mixture, the filtration will take less time.
Once most of the liquid has passed through the filter, use a rubber policeman to transfer the solid from the flask into the funnel. For a quantitative transfer, swirl a small portion (5-10 mL) of an appropriate cold solvent with the solid that remains in the original flask and quickly (while the solid is still suspended) transfer this mixture to the filtration funnel. Repeat the addition of small portions of solvent until all of the solid is transferred to the filter. (An appropriate solvent is one that will not dissolve the solid collected in the filter; usually the solvent from which the solid was just separated is appropriate.)
The video refers to a "clear" filtrate. Does "clear" mean the same thing as "colorless"?
Answer
No. Describing a solution as a clear solution indicates that the you can see through the solution and there is not a solid suspended in the solution, but does not provide any information about the color of the solution. Distilled water would be described as a clear, colorless liquid.
