Why filtering cannot be used to separate a solvent from a solute?
because the solute has already dissolved in the solvent so when filtering the solvent and solute go together... Filtering relies on the difference in sizes of particles of different substances. Solutes and solvents are commingled at the molecular level. There are methods of separating the two via chemical affinity that are sometimes referred to as "filtering" such as membrane separations, but they are not true filters. There are some very limited examples of filters that actually filter based on molecular sizes. Usually these are for filtering out rather large molecules or where the molecules can be made to cluster together to effectively form a larger particle. Cold filtering of beer is such an example where the cold promotes clustering of protein molecules (solute) which can then be filtered from the rest of the beer (solvent).
To filter or trickle through a porous substance?
filtering
Why cant you separate a colloid by filtering?
You cannot separate a colloid by filtering because the particles of a colloid are too small to be suspended by any filter. They will instead simply slip through the holes of said filter.
Explain why filtering can trap undissolved particles?
If the pores of the filter are smaller than the particulate, they cannot pass through and are trapped in the filter. The filter might not have small enough pores to filter everything out.
What type of filter paper does the company called Whatman sell?
Whatman sells various types of filter paper, including qualitative filter paper, quantitative filter paper, ashless filter paper, and high-purity filter paper. Their filter paper is used for various laboratory applications such as filtration of liquids, separation of solids, and sample analysis.

Why Whatman filter paper no 40 is used in gravimetric experiments?
Whatman filter paper no. 40 is recommended for gravimetric quantitative analysis. Some characteristics are: - flow rate: medium - Herzberg filtration speed: approx. 340 - porosity: approx. 8 micrometers - ash: max. 0,oo7 % - thickness: 210 micrometers - weight: 95 g/m2
