Question

Quizplus · Accepted Answer

Reverse osmosis is a process in which high pressure is used to force saltwater against a semipermeable membrane, which allows the water molecules to pass through while blocking the salt ions. This results in the separation of saltwater into fresh water and concentrated saltwater. Option B, C, and D do not describe reverse osmosis.
