Question

Concerning Their Permeability How Are Membranes Classified?​

Answer 1

Answer:

Membranes can be classified as impermeable, permeable, semipermeable or selectively permeable.

An impermeable membrane is that through which no substance can pàss. Semipermeable membranes are those that let only solvent, like water, to pàss through it. Permeable membranes are those that let solvent and solutes, like ions and molecules, to pàss across it. There are still selectively permeable membranes, i.e., membranes that besides allowing the pàssage of solvent let only some specific solutes to pàss blocking others.
