Filtration without a suction pump is __________________?
Show answer Hide answer
Answer: B. Slow process
Explanation
Filtration relying solely on the force of gravity proceeds without any external vacuum assistance. Without a suction pump to pull liquid through the filter paper, the flow rate drops significantly. Consequently, standard gravity filtration is characterized by a much slower operational speed overall. Laboratory filtration separates solid precipitates from liquid mixtures using porous filter media. Suction pumps create a pressure differential that accelerates the passage of filtrate through the barrier. Gravitational force alone provides very gentle driving pressure for liquid movement through filter paper.
Chemists choose gravity filtration when recovering crystallized products where the solid is the desired target. Vacuum filtration is preferred when rapid separation of fine precipitates is required during synthesis. Laboratory time management often dictates whether filtration apparatuses require mechanical vacuum assistance. Describing filtration without a suction pump as fast contradicts basic fluid dynamics and gravity principles. Calling it a rapid process ignores the time penalty paid when operating without vacuum pressure assistance. Stating all descriptions are possible is incorrect because gravity filtration is uniformly recognized as slow.
