Question

Why the flow of water is unidirectional in osmosis?

Answer 1

Dear Student, Osmosis is phenomenon of transport of water molecules and solute molecules from their higher concentration towards lower concentration through a semipermeable membrane. So, when we are comparing 2 solutions, there will be deficit of water on 1 side and excess of water on other(given both are not iso-osmotic), and then water can only move from in 1 direction. Regards
