Question

multiple choice question
which of the following is not a factor in tonicity?
selectively permeable membrane
impermeable solute particles
the electrical charge of the solution
osmosis

Explanation:

Tonicity depends on the concentration of impermeable solute particles, a selectively permeable membrane (for osmosis to occur), and osmosis (the movement of water due to solute concentration differences). The electrical charge of the solution does not affect tonicity, as tonicity is about solute concentration and water movement, not charge.

Answer:

C. The electrical charge of the solution
