After a Büchner filtration, solid is observed in the collected filtrate. Which of the following is the least likely explanation?
What is the main disadvantage of using a smaller funnel for a gravity or a vacuum filtration?
In gravity filtration, filter paper is often folded into a fluted shape, as shown. Why is the efficiency of filtration increased if fluted filter paper is used instead of a simple paper cone?
