what is osmotic pressure and osmosis pressure? |
| Answer» The pressure required to prevent solvent from passing through a semipermeable membrane from a region of higher concentration of solute to a region of lower concentration of solute is called osmotic pressure. It is also\xa0a measure of the tendency of a solution to gain water by osmosis when separated by a membrane from pure water.Osmosis is a process by which the molecules of a solvent pass from a solution of low concentration to a solution of high concentration through a semi-permeable membrane. It is a passive process and happens without any expenditure of energy. | |
