Verified step by step guidance1
Understand that filtration is a physical separation process where a mixture is passed through a membrane or filter with tiny pores.
Recognize that the key factor determining whether a substance passes through the membrane is the size of the particles relative to the pore size of the membrane.
Recall that substances larger than the pore size cannot pass through because the pores act as a physical barrier, blocking larger particles while allowing smaller ones to pass.
Note that other properties such as solubility limit, density, or boiling point do not directly affect the ability of a substance to pass through the membrane during filtration.
Conclude that the correct criterion for passage through the filtration membrane is the pore size of the membrane.
