Filtration Original Scenario-Based Practice

Questions

1. 1.

   On the floating research vessel Aethelgard, chemist Lyra collects an extraterrestrial river sample containing suspended insoluble volcanic ash flecks dispersed in an aqueous solution of completely dissolved luminescent salts. To harvest the solid ash particles cleanly while preserving the liquid solution without applying heat, Lyra pours the mixture through a conical glass funnel lined with porous cellulose filter paper. Based on the principles of filtration, which outcome correctly describes the separation of this mixture?

   • A) The dissolved mineral salts are retained on the filter paper because their chemical bonds exceed the pore size, while the volcanic ash passes through as filtrate.
   • B) The insoluble volcanic ash remains on the filter paper as residue because its particle size exceeds the pore diameter, while the dissolved mineral salts and water pass through as filtrate.
   • C) Both the volcanic ash and the dissolved salts remain trapped on the filter paper because porous barriers capture all non-water components of a mixture.
   • D) The entire mixture passes through the filter paper completely unchanged because flowing liquids carry all suspended particles through pores regardless of their dimensions.
