Question

the picture shows a filtration process. which of these is least likely to pass into the test tube?
liquid solvent
dissolved gases
solid particles
dissolved salts

Explanation:

Filtration is a process that separates solid particles from liquids or gases using a filter medium (like filter paper here). The filter paper allows the liquid (solvent), dissolved gases, and dissolved salts to pass through (as filtrate) but retains solid particles as residue. So solid particles are least likely to pass into the test tube as filtrate.

Answer:

Solid particles
